Its a stylishly decorated 2-bed flat atop a coach house. Its free standing so there is no noise from neighbors anywhere, and the street itself is tree-lined and with nary a passing car. If u want to be away from the hustle n bustle of central London, close to Hampstead and its 'village' feel and the Heath, then this is for u. Also, its only 5-7mins walk to either Finchley Road and Hampstead tubes (and Frognal Overground). It may be more expensive than some, but it is worth the cost if u want the above (ie. lovely place, privacy, great Hampstead location).
As regards the host, Amanda, she was super. Very kind, incredibly accommodating (we needed to extend our stay and were able to work something out no problems) and also helpful that she lives nearby. A++
