We had a lovely time staying at Paul's spacious flat. The place is light with high ceilings. Staying there feels like being a guest at someone's actual apartment - there are real books (not tour guides) on the shelves, real posters (not pictures of Big Ben) on the walls, and basic cooking ingredients in the kitchen. There's a big bedroom facing the street and a living room facing the garden which has a large comfy couch you can easily sleep on.
The flat is in a beautiful quiet neighbourhood but not isolated - there's a great breakfast place just up the road and the tube stop a little further down. You can see a train line running not far from the property on the map which worried me a little but we barely heard anything, nothing at all during the night.
Check-in and check-out were seamless and Paul was very responsive to any queries over text.
