@no name found - sure I''ll give you some advice.
Not sure if you have a car at your disposal and what your budget is, but let me try to give you some options.
Girls working in the streets:As mentioned in other posts you have the Nigerian prostitutes on the Ramblas at night (avoid) and gipsies, older women (50+), (again) Nigerians and a single Romanian girl working in the calle Robadors.(day/night) Also not recommended. During the day there is plenty of police present, but at night it's not the safest area.
Its completely different near the football stadium (Camp Nou) at night. In the summer starting around 22:00 until 2 am and in the weekends up to 5 am (depending on how busy it is). mind you, if there is a football match, there wont be any women.
You will find here young and often very pretty eastern european girls. I have attached a map and drew a yellow line where you will find these women. The area with the red crosses is an area you dont want to go to, unless you are into shemales. Stay on the yellow line and you will find real women. Prices 20 for a bj /30 for sex
Its easy to get there with the metro (green line) and some girls will service you while on foot in the nearby carpark, however a car is recommended.
Independent women and agenciesThere are many independent women and agencies in barcelona and the prices starting at 50 euro for 30 mins and the average hourly rate is 120/130 euro. There are many sites where these ladies advertise, but I would recommend avoiding the classifieds sites like e.g. pasion, because of the many fake ads and the fact that its only in Spanish.
I dont know your level of the Spanish language, but these women often use slang and Google translate doesn't handle this very well. It can be very confusing e.g. A titty fuck is a corbata francesa which Google translates as a French tie

However if you do speak Spanish then sexomercadobcn is a good place to find women and if your level of Spanish is limited, you might want to try an app which is pretty popular over here in Spain and is called Blackbook App. It's basically Tinder but with escorts and doesnt require you to download or install anything ( because its a web app)
All the info here is in English,the only downside is that while this app looks great on your mobile phone, it does not on a desktop.
But hey when you are over in Barcelona you will probably browse on your phone for women and then you will this a very helpful tool.
Here is an example of the type of girls you can expect to find in BCN

External Link/Members OnlyThe only thing that could be an issue is communicating with these women, most of the independent women only speak Spanish and their knowledge of English is pretty basic, but often just enough to setup a meeting.
As for the agencies, the communcation issue doesnt exist. The people answering the phones all speak English.
There are a few agencies that stand out in terms of quality of women and reliability. I would recommend Apricots (2 brothels), Felinas (2 brothels) or Angeles de Devorah (smaller agency, but nice women). All have a selection of attractive women and prices start around 120 euro per hour for standard sex. They will charge you extra for any special stuff.
And then there is Haima, which has 5 locations thoughout the city and the prices start at 40 euro for 20 mins. Too be honest not too sure what the quality of women is like and what you can expect, but if you are on a budget you might want to check it out. They have 150 women, so pretty sure there will be something of your liking.
Thats all for now. Let me know if you have any more questions. Glad to help
