Mahir's apartment is well located on Camden Road as several buses lines allow you to be in the city center in no time.
On the 3rd floor of a building, you will have a nice little room with convenient and renovated amenities.
The building being at a crossroad, the noise from the street can be a bother if you sleep at night, especially considering that the windows are not very well soundproofed. Another complicated element to sleep is the green light from what I believe is the fire alarm. The Wifi doesn't work most of the time, and the door doesn't close well. You cannot double lock it. Although we didn't have any problem during our stay.
The room is clean and Mahir was nice enough to let us put our luggage before 2pm. He is very easy to communicate with and will answer your question extremely promptly
