1 room apartment of 50m² in London

We are a couple leaving our lovely London home for two months (July and August) and we are looking for someone to enjoy our home. The flat is a spacious two-bedroom property located equidistant between the Kentish Town and Chalk Farm Northern Line tube stations. It is a 10 minute walk to Hampstead Heath (paradise during summer!) and 40 minutes on foot to the British Library. All the major universities in Central London are close by. The building is a Victorian conversion and it is at the end of a road that has markets on Thursdays and Saturdays. It's a relatively diverse neighborhood and close to good supermarkets. The flat itself is on the second floor and gets light from both sides of the street. We have lived in this flat for about a year, previously lived across the street, and have been very happy with the location and the neighborhood's safety. We have a cleaner that comes bi-monthly and we will leave cash for her.
