We had a great stay at Peters place. It's a little bit out of London but easily accessible via train quite close.
The flat itself is very comfortable and larger than expected! The beds are comfortable and all amenities you'd hope. The Wi-Fi is good. We felt very safe in the area too. Communication with Peter/Janet was great and prompt and we were met on arrival.
Highly recommend this place for more space than you would get closer to the center. Thanks!
