This was a wonderful place to stay! Nicola is a great host. After she showed us around the flat, we ran into her while we were trying to find the neighborhood restaurants and shops. Even though she wasn't going that way, she walked us to the street and even helped us get a table in one of the restaurants.
It is an easy walk to the Tube, and Regent Park is right across the street. There is some traffic noise, which can be a problem during the day if you want a nap. However, earplugs took care of the problem for me.
If want a charming flat with easy access to all that London has to offer then choose this one.
