I enjoyed a lot my week at Yan's. His flat had everything I needed and it felt like home from the very beginning. Also everything is as the photos suggested. And the yoga room is really relaxing.
The flat is near Harringay Railway Station (Zone 3) and a 10 minutes walk to Manor House Tube Station (Zone 2) on the Piccadilly Line, which goes straight to City Center and Heathrow Airport (in 1 hour and 20 mins). In its proximity there are plenty of restaurants, groceries, pizza places, a Tesco Express and a big Sainsbury's at Harringay. And Finsbury Park, where I used to run at 7pm being surrounded by rugby, football, basketball, baseball and tennis players (it has great sports facilities).
Yan was always available on -Skype- and he's a great host. I recommend passionately a stay at his flat and I would definitely come back to his place.
