The apartment was cozy and identical to the pictures Flo has in the description. It is a nice option if you are just two.
However, the apartment was too tight for 4. There is just a really small table to eat and it just had just two chairs. The living room window, where the sofa bed is located, is really big and with no curtains at all, so no privacy to get changed and lots of light coming in during the night and in the morning. Also, the sofa was really hard and not a proper sofa bed but an extendable sofa.
Besides that, the experience was ok.
