Spent a week at Nicla & Paolo's flat. It was clean, quiet, and comfortable. There was plenty of hot water, and the heating was quite good. Never got cold. Bed was comfortable. Got a good night's sleep every night. The bathroom has been recently remodeled, very nice. The true glory of this flat is the kitchen. It is the most well appointed kitchen of any airbnb I have ever stayed at. If you like cooking your own meals, you well be happy here. (OK, one dinner plate was chipped, and it was hard to balance the espresso pot on the top of the stove, although there is a single serving pod coffee maker if you are into that sort of thing).
A couple of logistical matters; if you are coming in by the underground, the charge from zone 1 stations to bounds green is 3.30£. The walk to the flat from the station is a bit more then 1/2 mile. If that is a little to much for you, you can get off one station earlier (wood green?), and take a bus north a mile or two (about 1.5 £), and it will put you 1.5 blocks from the flat. Google maps can give you the proper bus numbers. If you do this, it also gives you a chance to do your shopping at the Morrison's grocery right at the wood green underground station. There are two or three quite nice, small grocery stores, near the flat, but of course they don't have as big a selection. I took the underground into London (Russell Square station) for four days, the trip takes about 20 minutes.
The key to the entrance to the building is a little touchy. Be gentle, don't try forcing it to turn. Never had a real problem getting it to open, but it does require a little jiggling. I was very happy too stay here it suited me perfectly. Not the penthouse at the four seasons (not that I would know). But if you are looking for a clean, quiet place to stay with a terrific kitchen, within reasonable distance to downtown London, i would highly recommend this spot.
