The apartment location is really good, it's not too far from the tube and also there are several bus stations right outside, also plenty of bars and restaurants at a walking distance.
Carolina communicates very fast at answers to every questions you might have, also she has a lot of good recommendations about restaurants around.
The apartment can get little noisy from Friday to Sunday during night time, but it's not too bad.
There weren't any issues at the apartment, other than a repeating "clicking" noises coming out of the heater unit in the bedroom- which was kinda disturbing specially because it's right where your head is. Carolina sent a maintenance guy to repair it, but the problem came back the day after.
In general, the apartment is really great, and located at a super convenient location, and it's really recommended!
