It's a nice size two bedroom in a security building. You pick up the keys from a porter and walk around back to the entrance. The building felt very secure and clean, the rooms were large for London and it was nice having a large dining room table and washer (no dryer) in the flat. The refrigerator is new and oversized for London. The area around the building appears pretty nice, not Kensington but lots of BMW's. I was amazed at how quiet it was at night. Some people in the building/floor smoke and burn considerable incense which can get pretty strong unless you open the windows. The walk to the tube occasionally had some sketchy people hanging out, drinking/smoking and some of the mico marts had their glass smashed in while we were there. Stores and ATM less than a block away. It is a half hour tube ride to any attractions and a hour and a half to Heathrow Airport.
Complaints? Well the second bed could be bigger (its a fold out on a love seat) and the apartment has some wear, needs some light bulbs replaced, new flooring in the kitchen, kitchen counter and hob (stove top) are damaged but work well enough. Overall the price was good and it met my family of five's needs for two weeks. We had a great time. The host was quick to get back to me when I needed assistance.
