Great experience overall. Would definitely stay again. You are a little far away from the tube, but only a 5 minute walk from the 43 bus, which runs frequently. It get you downtown relatively quickly and it's cheaper than the tube is anyways. It takes about 90 minutes to get to or from the airport (43->Piccadilly Line). You can also walk a bit more than a kilometer to Muswell Hill which has a good variety of shops and restaurants including grocery stores and a 99p store.

Positives:
=Incredibly clean
=Comfortable bed with good sheets/blankets
=Microwave, mini stove/oven and a real sink helped us save money on food
=Beautiful/quiet/safe neighborhood
=24 hour bus (relatively) nearby
=Very responsive host, always replied right away.
=No hassles with check in or out.

Negatives:
=Pretty far from the tube
=No stores or restaurants within a 0.5 km
=Toilet is one of those pumping kinds. It makes a lot of noise when you use it and sometimes it clicks on when you aren't using it (like in the middle of the night).
=Often got knocks on the door from people looking for the upstairs apartment. That can be an unpleasant surprise.
