I know there are several other review threads on LMP but I searched and did not find any that have a review of the new location (sorry if I missed it and needlessly created a new review thread).
The new location is very nice. This was my third LMP; my first was at Lancaster Gate and my second was in Westminster. The flat is very convenient to Edgeware Road station and easily walkable from Paddington. It is on an upper floor (forgot to count but probably the 3rd or 4th floor). You enter and are escorted into a 'changing room' which has two wardrobes with ample hangers. You put all valuables into an envelope which you seal and sign are given a robe and shown to a bathroom for a quick shower in one of the two toilets -- one off the hall and one off the back play room. There are three play rooms --- one with two twin beds, one with two double beds and a chaise lounge like thing, and one with three double beds and a chair. It was not a issue during my visit but there was not a lot of air movement due to the heavy curtains on all the windows. Based on the location of other buildings, opening the drapes is probably not an option so air movement could be a problem and not sure how comfortable the flat would be on a very hot day. The flat was clean and nicely presented with plenty of clean towels in the bathroom and ample hot water even though I arrived a few minutes after the party started and several other punters had already showered.
Sorry, but I did not catch the names of the girls nor did I remember to capture the line up from the website. I am not sure if they exactly match the pictures on the website but, if not, they were reasonably close photos. I certainly found them all attractive. There were two in particular that had very nice tight bodies with stunning natural (C/D cup) tits. There were also several that might not meet the tastes of all. One was heavily tattooed with a large tattoo on her back. Another was a definitely a BBW, but I thought she carried it well and she had a great personality. There were a couple that had tight bodies but had boob jobs. All were very friendly and very actively engaged for the entire session.
For those that have not been, it is an amazing experience to walk into a room and see one hot girl getting fucked from behind as she gives a blowjob to a guy in front of her, another cutie riding a guy cowgirl, a third hottie getting fucked in a chair, and then having the best looking girl in the room look up from a blowjob to INSIST you start playing with her. Over the two hours, I was able to either fuck or get sucked by (I really like oral so that often was enough for me) from 6 of the 7 girls. I am not a multiple pop kind of guy so not all were to completion but it was not for a lack of opportunity or lack of effort from the girls. The best part was at the end there were only four guys left and I ended up having two girls take it as their personal challenge to get one more orgasm out of me -- double blow job, hand job with boobs in my face, dirty talk with pussy in my face -- it was like a teenage wet dream.
The only downside was one punter who showed up late and clearly needed to spend longer in the shower. To their credit, I believe someone must have said something to him as he 'cleaned up his act'.
Based on all the information on UKP, I knew what to expect and my expectations were definitely met.
A few other points/observations:
As stated many times before on UKP, there is not a lot of modesty at these parties. You are provided a robe but if you are uncomfortable with male nudity then you might not enjoy yourself. You never come close to 'crossing swords' but are often spit roasting a girl while another punter is getting oral on the bed next to you. Also, punters will tend to 'share' boobs of the girl next to them so you sometimes run into another guy's hand with your hand.
This is not a passionate, GFE experience. Not to say you won't get passion, one of the girls may have qctually cum while getting fucked and several others had very cute sex noises, but there are a lot of distractions. The girls will engage other punters if they are only working on one and, while the girls were all very good about focusing on whoever they were engaged with, there was some banter between them while they were 'engaged'. Also, there are two women who roam the flat cleaning up, replacing baby wipe packs, replacing towels in the shower, etc. who have wicked senses of humor and don't mind a little banter.
Both girls I asked allowed touching and finger insertion into the pussy but I am not sure how wide-spread that is. It was common to see punters rubbing butts or cupping breasts of another girl than the one they were engaged with.
The standard is for girls to use baby wipes on themselves and you between engagements. I did not see any girls shower during the two hours. As an aside, I cannot imagine the amount of wipes they go through. What do you say when checking out with a trolley full of babywipes, "I have sextuplets"?

I did see some RO but it did not seem common and at least one of the girls seemed uncomfortable with it when it was requested.
Another punter inquired about CIM but it did not seem to be on offer by any of the girls. Interestingly, it was not a straight no -- he was told she did not do it but she asked the other girls in the room if anyone working that day offered it, so seems like that it is possible but not promised.
All the oral I saw was OWO.
I did not see any lesbian action, even though two situations could have easily led to a show. The first was when one girl was getting fucked doggy style on the floor at the end of the bed while another girl was giving a blow job on the bed; she literally had to move her head to one side to avoid getting a face full of pussy. The second was with two different girls when they were trying to get a last pop out of me. Neither initiated any sort of lesbian show nor any lesbian dirty talk.
Food and drink were provided in the kitchen as well as some quality discussion about the recent World Cup results.
