We had a good stay at Cityspace Bermondsey. By chance we could check-in in the morning morning much before the usual time and start our stay in London earlier. The room is cosy and clean. The sink in the bathroom had a very strong smell though and this had not been fixed before the end of our stay. We also appreciated leaving our luggage until after the check-out.
Overall this has been a convenient accommodation even if the communication was not straightforward through the two channels, Airbnb and CitySpace.
