Very nice appartment with 1 floor. Be careful if you don't want stairs because there is one to reach the apartment, and one inside to reach the room.
The room is peaceful and super clean, as all the apartment. You'll have access to the kitchen if needed. Mina is quick to answer messages prior the arrival but also after. She's a very nice and discreet person. As previously said, light from sunrise can bother, but a sleep mask will definitely help. Apartment is easy to reach by bus from St Pancras and King's Cross. Will definitely come back again.
