We had a wonderful time at "Heart of London". everything was just like in the description and the communication was easy and always quick :)
The room, aswell as bathroom and kitchen were very clean and everything needed was there. The AirBnB has a very good location, thanks to the bus and subway stations nearby you can go everywhere in a very short time. Aswell you can go to different spots by foot.
The district Pimlico is very calm and nice, we were 100% happy with our stay at "Heart of London" and we will keep it in mind for the next time in London.
