Andrea's house is beautiful. We had a detailed description of how to enter the house and had some fun for the "treasure hunt". The house was big and comfortable. My daughter loves the children's room and those toys. The kitchen was very modern and well-equipped.
We were pretty unlucky that the hot water at the bathroom was pretty unstable during our stay. I would say Andrea did his best since he was not able to be there.
All in all, we did enjoy our stay in London.
