I would like to say that Alexander's flat is exactly more beatiful than what is seen on the photographs. The studio was very clean, tidy, comfortable, spacious and bright.
Location of the flat is also good and well connected to all parts of the city. Nearest tube station is in 10-15 minutes walking distance but there is a bus stop just 2 minutes away from the apartment. In my opinion, bus is better alternative for transportation while staying at Alexander's flat. There are many bus lines including night buses providing access to everywhere easily.
Also, Alex is very nice person and great hosts that I am very glad to meet him. He was very helpful. There was a small wi-fi connection problem at the beginning but he has fixed it immediately. He was also flexible in check-in and check-out time. I really recommend Alex's flat for enjoying London and I will not hesitate to make reservation for my next visit to London once it is fixed.
