This flat worked out perfectly for our party of 4 (2 couples) visiting London from the U.S. for a 7 day vacation. The two bedrooms and two full baths allowed each couple their privacy. There was a washer/dryer and dishwasher. We air dried our clothes using the available drying rack because in my past experience, the European washer/dryer combos leave a little to be desired, and it worked out perfectly. The kitchen had a fridge, freezer, oven, range, electric kettle, french press, silverware and basic cooking pots, etc. so there was everything we needed to make breakfasts in the flat as well as dinner a few nights. The beds were comfortable full size beds and the bathrooms were very nice, one with a giant, very clean tub that I did take advantage of and had a hot bath after a rainy day. The living room was a nice place for the 4 of us to gather at night to chat or watch TV. There was a nice selection of channels.
The location ended up being very convenient. I wasn't sure at first if it was too far from what we wanted to see, but since we were going all over London sight-seeing, as well as up to York and to Oxford by train, we found the Baker Street station an easy and quick hop to pretty much everything we wanted to see. We even went straight to Oxford from the even-closer Marylebone station. There are nice pubs a short walk away as well as other restaurants and nice shopping on Marylebone High Street (10 minute walk).
Christopher was a great host and greeted us with keys and a tour of the flat when we arrived. He also stopped by on our last night to say goodbye and ask about our trip. In addition, he provided some nice amenities to be sure we were comfortable when we arrived (ie milk, coffee, tea, as well as some starter soap/shampoo, etc.). We had a very nice time and a lot of it had to do with our experience with Christopher and his flat. We hope to be able to come back soon!
