The location is convenient, around 5 mins walk from Euston, 3 mins to British Library, 8 mins to King Cross. Easily access to underground and bus. The room is clean and tidy, enough for 1-2. Heater is worked and window can open.
The room I lived in is seems like slightly different with the Ad's photo though, not sure if it's the same room with the Ad's post. And the room is on the lower ground floor. Four rooms totally in the flat and two rooms+one bathroom in each floor separately.
There are some "sounds" at day and night. I guess probably it's from underground or maybe train. If you are a light sleeper, you probably feel annoying about the sound.
