Location, location, location! I loved staying in Nelly's flat. It has an unbeatable location that while in the middle of so many things is on an incredibly quiet street. The flat has all of the necessary amenities and benefits from great light. The bed is lovely, big and comfortable. Only downsides may be the walk up the stairs and that the furniture in the reception is on the dated side. But these are small issues that are overcome by the many positives.
Nelly is a superb host who takes great interest in your stay going as smoothly as possible. I would repeat!
