This place has everything you need. I stayed there for a month and had any trouble.
Confortable and great location, very close to the underground station and lot of commerce at the surroundings.
Good Wi-Fi connection. I used the internet for Youtube, Netflix, voice and video meetings, and it was pretty stable.
The communication with the owner is very easy. Everytime I needed any kind of support, he would answer my texts or calls quickly. He is a nice and thoughtful person.
I am very satisfied with this place. Definetly recommend. If I could live in London for more time (I wish I could) I`d like to be in this place.
