I could not check in on the day I planned to. My flight was delayed for about 3 hours. By the time I reached to this place, Marc was unavailable. I had to check in a near by hotel for that night. I contacted Marc next day, and he put me in touch with his friend who helped me to move in.
The room heater was not working throughout my stay. Therefore, I had to live there without the heating.
Although, the location of this flat is very convenient- as described in the advert. It has good connections from Heathrow airport. Furthermore, the flat is surrounded by lots of restaurants, and shops.
