Sebastian was very easy to stay in touch with, and was flexible with accommodating our early arrival. This was very helpful to us! The flat has everything you need for your stay in London- having access to laundry machines was wonderful :) It's in a great location that is close to the main attractions and still near all the necessities (grocery store, pharmacy, restaurants, etc.). It was a nice place for us to relax after a long day of sight-seeing. Would definitely recommend!
