This is a lovely, quirky home in an amazing location. The Camden High Street is very busy and noisy, with lots of shops, restaurant and pubs. It is just a few minutes walk from the High Street to this quiet, charming street with lovely gardens and well kept homes. Regents Park is in easy walking distance. There are two local tube stops quite close, so it is easy to get anywhere you want to go in the city.
The home is quite comfortable, with features that are unique to an old house. Given London's weather, it is really nice to have a clothes dryer available in the flat. (You don't have to worry about running back and bringing in your laundry when an unexpected rain shower begins.)
The spiral stairs, mentioned in other reviews, are an acquired skill, particularly if you are carrying something in your hands, as they are quite narrow. I thought they were fun, but not everyone agrees.
Kerstin is a wonderful host and clearly wanted us to have a good stay. It was a pleasure communicating with her. I would recommend this host and property if you want to stay in central London.
