I had a wonderful 10 days at Pilar's place. I was welcomed warmly and after my long flight was offered to share dinner, which was fun with lots of laughs. I had great conversations with both Pilar and her son. Nothing was a problem when had a question.
Plenty of transport options and easy to get to from Heathrow - 2 tubes and a walk.
Excellent host, highly recommended and would definitely stay again!
