We stayed 6 days in Sylvain's very cozy, clean and luxuriously appointed apartment and really felt comfortable. The beds and bathrooms were without blemish and everything worked perfectly. The location of his flat in Hackney is central, but quiet and even the building has a concierge. The transport links by bus, tube or overground in the city are excellent. Sylvain is a very caring owner and had a lot of very good and useful tips prepared. For questions he was always available for us and helped us a lot further. We found it very helpful, that the apartment also has additional 220 volt power connections with European outlets.
We can absolutely recommend Sylvains flat and will stay there again at our next London trip, if possible.
