It's a lovely place, but with some drawbacks.
Pros: great location, very clean, comfortable bed.
Cons: It is up 3 flights of narrow stairs that are difficult to navigate with luggage. Lights were out in part of stairway when we were there. The loft bedroom looks cool but is pretty tough to sleep with a beam two foot above your head. The stairs have no handrail so it is tricky getting down. The worst part was you could only turn lights on with a key, and the key could not be left in the flat since it was attached to front door/apartment door by a small padlock. If you have more than one person, that means, if one leaves the flat - you either take all keys, and then no lights in flat for person left behind, or you don't take the keys, and the other person has to go all the way to first floor to let you in when you return.
