We had a great stay at Claire's place. Everything was just like shown in the pictures. The views are amazing, though quite a lot of light at night coming form the City!
Even though she was not in London at the time, we had no problems getting into the house and we had a person to contact in case there was anything we needed.
The location was very convenient to visit London and we even found 3 Oyster cards in the house which we could just charge and use during our visit!
