I am planning a trip to London for one week in march, I have been looking at many apartments (for 3 ) but it's very difficult to decide. Did anyone use London Connection agency? They have a very nice one bedroom listed across from Gloucester Rd. tube, it is on the 9th floor, looks new and beautiful for $270/night.
The agency is in USA and does not charge any extras.
Please help

I don't know that agency, but I used to stay in that neighborhoood quite often when visiting London. It's a great location. I trust there's a lift in that building!
