Location: The flat is located at the edge of zone 2, so the tube fares will be those for central London. The tube station is just under a minute away from the appartment, which is really all that counts in London (expect to be travelling by tube a lot). Two supermarkets are located near the flat, with one being very reasonably priced.
Room: The room is very big, clean and bright. The windows seem to be a bit thin, as it can get quite noisy at night. Also, at night it is not really that dark in the room. However, we've slept every night without any interruptions.
The flat: Nice, small flat. The flowers on the table were replaced frequently, and everything was clean as well.
Bathroom: The bathroom was clean, too. It is equipped with a bathing tub which also serves as a shower.
Kitchen: You can use the kitchen freely. Also, some of the food is available for you.
Host: We did not meet Rey in person. Instead, Magaly hosted our stay. She was very flexible with our arrival (9 AM) and departure (7 PM), we were allowed to leave our bags at the appartment. Also, she was very caring (asked if our blankets were warm enough, etc).
