Helen flat has an excellent location. Just in central London. Buses, metro, train are at hand. Walking distance to everywhere: markets, convenient stores. There are two open 24 hours. The flat is in the 4th floor and it has a lift. Helen was waiting for us with a bunch of little details as flowers, juice, cereals, croissants and much more. All the appliances work properly and Helen herself have us all the instructions to use them. There is a green binder with all of them. The comunication was excellent. It is very easy to get in touch with her. Thanks Helen. You are really a superhost!
