Our stay in Belsize Park during the long bank holiday weekend was very nice. Although we arrived in the middle of the night we felt directly welcome in the cosy and fully equipped studio. Even the refrigerator contained some snacks. The surroundings are nice and very quiet but still public transport via (night) bus or underground (Norther Line) is available within 5 minute walking distance. A supermarket, several cafes, restaurants and some small shops are around the corner. Camden and Hampstead Heath are great if you want to do a longer walk. If there would have been any problems (which were not) we could have asked the building manager Phil.
Thanks for the nice stay, Manuela and Stephan
