The area is really safe, we were walking really late at night in the neighborhood with my friends and never had any trouble.
The flat is really nice, comfy and cozy. The place is clean, there is everything you need, even netflix on the TV in case you plan a chill and relaxing night at home during your stay.
The location of the flat is really not far from the center town and there are two tube stations not far from ! My fav one was Tufnell park, it was really nice to see all these beautiful houses on the way to the tube station.
Moreover, even if you hang out late at night, you can manage easily to come home by bus. There’s the line N29 that comes from the good placesh and the center town that can bring you home, and the bus station is about 5min about walk to the house.
