We had a lovely time in this apartment and enjoyed it very much. Martin was really thoughtful and helped us with anything we needed. The apartment is spacious, especially for London. We were 4 people and had no trouble fitting and making ourselves comfortable in the apartment. The place is in a nice quite street (the other side is a bit loud due to the traffic on the main road) and just a 8 minutes walk from central line. To get to Oxford Circus takes approximately 25 minutes, which is great for London. The big shopping mall is also very convenient, since it hosts the largest movie theatre I have ever seen and all the shops you can think of.
Finally, the place is great for a business trip or just a holiday in London. If you miss anything in the apartment, Martin is always there for you to fix it or help you out!

Enjoy staying there! It feels a little bit like you are in the movie Notting Hill :)
