The flat is comfortable, clean and calm - everything is exactly as in the description. We had everything we needed - a great and well equipped kitchen, a very clean bathroom with a well functioning shower (with always enough hot water :)), a very comfortable bed. We didn't meet the host, but Nick was very helpful and always responded very quickly to my emails.
The only minus was that it always took us up to 1 hour to get into the city center (e.g. Picadilly Circus). But there are several bus stops around and an Overground station, so the public transport connection is actually very good. Plus we loved the neighbourhood! It's so much more relaxed and authentic than the touristic and overcrowded center of London. There are several small supermarkets around, and some really good small restaurants and cafes.
A great place to stay for a couple or a single person - I would definitely recommend. Thank you, Nick!
