Great value choice if you wish to stay near Waterloo station. Room is filled with useful and modernly designed amenities.
The downsides: would be great to have a separate and private entrance though, as it could be a bit awkward walking through the wine bar in the evening lol; couldn’t use airplay or Netflix on TV; room could get a bit smelly as there was no window to open.
Therefore the place is great for a couple of days but not sure about long stay.
