I have stayed here before and find the flat to be in a great location ( literally 3 mins from Belsize tube station) and a good size for 2or 3 people . In fact quite spacious compared to other London flats . Sheets and towels are plentiful and good quality , the bed is large and comfy and kitchen is great . Washer and dryer are a plus as is the small shared courtyard.
Really is a place I will keep returning to !
