I truly had an enjoyable stay at Martin's place! It is located in a lovely neighbourhood of Putney which has great access to public transport (train station is nearby and there are plenty of buses in the area). The surrounding of the flat is tranquil and silent even during the daytime which is perfect for relaxing and good rest.
The flat is newly renovated and all amenities are in excellent condition. It is very well equipped and basically there is nothing to worry even if you are having a long stay here. There is also a garden facing the flat which provides good sunlight!
Martin himself was an excellent host. Despite being away, he was very responsive to all messages and made sure that everything was taken care of. In short, I would highly recommend this place to anyone.
