I stayed here with 2 other guests (3 in total) for a little less than 2 weeks, and the flat was an extremely cozy one with lots of natural day light and in an incredibly prime location. Quite frankly, it was everything we asked for and is as listed. On one end of the street you have Oxford Street and on the other you have a straight shot to West End and Leicester Square, you really can't ask for anything more central if you're looking for a prime location to all the main attractions in London.
Matt was also an extremely hospitable host. Didn't get the chance to meet him in person with all of the things we ended up doing in close proximity, but anytime we had a question Matt would respond within the hour and with suggestions on what we could do in the area. We had an early flight in and a late flight out, but fortunately Matt was extremely generous and understanding in our schedule and helped to arrange an earlier check in and later check out for us.
All in all, this was a super cozy flat that was made even more perfect by the fact that it was close by all the places that you would want to go to. The flat also overlooks a number of cafes and restaurants so it's also in a lively (but not overwhelming!) area to people-watch as well!
Thank you for everything Matt!
