We had a nice stay at Ben's place. The room is a tight squeeze for two people, but we anticipated this - it is fine for a couple of nights. It is tastefully furnished with a very comfortable bed. Towels, bathrobes and slippers are provided. There are five rooms in total with two toilets, a bath and a shower shared between them.
The communal areas are cleaned daily. The bathrooms are well maintained and the kitchen is stocked with pretty much everything you'd need - the Nespresso machine was a great touch.
We were in the room next to the bathroom and it can get a little noisy in the mornings if the shower is being used, but this wasn't a huge problem for us.
The place is in a quiet residential neighbourhood close to central London.
Ben is easily contactable and happy to help with any problems.
