Great place and great people.
I don' t know where to start, because I feel thankful and enthusiastic. This is an extraordinary place, ideal für a trip to London, with everything nearby: shops, tube, bus. You can get into London and back to Belsize Park and its tranquility and quiet, easily. The apartment is quiet (London is loud) and very nice, the room you stay in has a good size, the bed is comfortable (with cotton bed covers), the windows can be opened, the kitchen is well supplied and the bathroom beautiful. You also get things you need daily: towels, toilet paper, water heater, spices, water - also drinkable from the tab - and so on. I highly recommend staying there. Chris and Renata are great hosts, supportive and well organized. Printed plans for orientation and the informations you need to get to know the whereabouts are on the table and Chris kindly helps if you need anything. I have not been to London before and enjoyed the quietness of Belsize Park after long days out in the hustle and bustle of the city. I stayed 5 days and will come back.
