Everything looked like in the pictures and the description, the place was super clean and the other guests were respectful. There are 5 rooms in total with 2 bathrooms to share. All worked pretty well.
I don't advise coming with big suitcases, since the stairs are quite steep. And because the property is located on a busy avenue, it's handy if you have ear plugs to sleep at night.
Closest metro stations are King's Cross St. Pancras and Russel Square. I walked to the British Museum and even to Tate Modern, so location is great.
I will definitely stay here again when I come back to London.
