Lovely place. I really enjoyed my one-night stay. Everything i needed was there. Close to Kings Cross and St Pancras, but a fairly quiet street. Some traffic noice in the kitchen/lounge with sofa bed, but the actual bedroom was very quiet. Nice shower. I'll stay again if i'm back in the area. The man who checked me in, Swartz, was very helpful. I was given clear instructions on how to use the door locks, wifi etc.
The only issue i had was that the listing says Bag Drop Off allowed. But it wasn't. I found a shop on Grays Inn Rd which offered this service, but I felt a bit uneasy leaving my stuff at a random shop. I would have preferred to leave it at the place i had stayed. You can leave luggage at the station but i needed to collect after their closing time. Overall a good place to stay.
