I stayed at Ed's place with my parents and my girlfriend over the weekend. We haven't met Ed but he was always very reactive to answer any question we had before and during our trip. He made sure we had everything needed to enjoy our stay. The apartment looks exactly like the pictures so no bad surprises here. It is beautiful, spacious, very clean, light and well located (15 min away from Victoria station walking). Ed arranged for John to give us the keys at our arrival, John was punctual and very friendly, he also made sure we had everything we needed to have a great, comfortable stay and gave us some good tips on where to eat in the neighborhood.
Our overall experience was amazing and we warmly recommend Ed's place for a trip in London. :)
