We had a five days stay in London. Olya was the great host, eager to answer any questions. Location of the property was great: it was safe and calm and at the same time very close to the tube and therefore 20 minutes away from all the London fun. Multiple good breakfast-lunch-dinner places are also nearby, within 5 minutes walking distance.
The only issue was a winter blanket that was a certain overkill for the current London hot weather but Olya was very cooperative in solving this problem for us.
Great stay and great host overall.
