There is another place, about a block away and a bit smaller (I forget the name) but is similar to Chelsea Cloisters (CC) in that it is a serviced apartment building, with a very "anonymous feel" to it and lots of comings and goings - tourists, residents, visitors and others. Never any questions, or even a look in many cases, from the front desk when you go in and rooms seems adequate, if a bit dated. As a punter this is exactly what one is looking for. Maybe hotels are another option, but you have to check in/check out and there can be "issues" with access late at night. I imagine apartments in CC are booked long term and various girls just rotate through them. For me, London based, it is ideal - anonymous, close to public transport and with rooms that are fit for purpose.
