The location is very convenient, especially for a short-time visitor wishing to explore the city - the Chalk Farm tube station is just around the corner, so you can get to the very center in 15 or 20 mins.
Across the small bridge there is Primrose Hill - a fancy area with a lot of cozy cafes, book shops etc.
Sofi and Tilly were polite and considerate, always ready to offer help or to answer a question.
