Our stay at Sane's place was great. Sane is really helpful and will get out of his way to make it easy for you. Communication was efficient.
In term of location, the apartment is easily accessible via public transport and give a nice view on the North part of London: Shard & Walkie-talkie. The bathroom was sparkling clean and the bed was really soft. We loved it.
The apartment well equipped and sound proof (with the exception of the numerous crimes in London).
Would definitively come back.
