Very close to Hyde Park and two underground stations. The surrounding area and the building seemed safe and quiet. We enjoyed our stay overall, except for some inconveniences.
Not enough space on the floor for our luggages so we had to move the bed a little bit to make space. There was only one table which was already occupied with kitchen tools, and no chair, so we had to eat from the bed.
The wifi worked better at only certain parts of the room, closer to the door.
