Nadia was really accessible and communicative during our 4 night stay over New Years. The key handoff and check out were very smooth. The flat is a lovely, cozy studio and gets a fair amount of light; it does face a petrol station and the main street but the windows block out most of the sound. I was working remotely during the time, and the wifi was steady. The location was also really convenient—right by the rail and underground for Victoria/Picadilly, easy walking distance to Highbury & Islington and the best Turkish in the city in Wood Green, shops and restaurants on the other side of the rail station, with a corner store right next block. We used to live in the city and were just returning to visit friends, so weren't looking for anything close to tourist spots, but they're also easily accessible through the underground. The only warnings I have are that the washroom sink's tap is quite sensitive, so take care with the spigot handle, and don't flush the toilet if someone's in the shower. I can definitely recommend Nadia's flat if you're visiting London!
