Petr's home is indeed a neat place to stay, clean, cozy and fully equipped. It served as a great base camp during our visit in London as it's very conveniently located with frequent bus services from nearby stops. It takes merely 5min to get to the Lewisham DLR station. Local Sainsbury's is a 5 min walk.
While we hadn't got a chance to meet Petr in person, he was always available and responded promptly. We really enjoyed our stay and would recommend the place. And kids loved to slide down the stairs, but that's probably something Petr should have never learnt about ;)
