I stayed there with my girlfriend for 2 nights in mid jan. Good location, in a not so touristy neighborhood, walking distance from everything. Public transport was close too. The apartment, more than a monolocale, is an independent room with a mezzanine, taken out from a bigger apartment. Main issue is the lack of space cause the mezzanine floor, where the bathroom is, is so low (i'm 176 cm) that requires you to sit on a small chair inside the shower to wash. Being two guests, i was forced to open the couch-bed on the ground floor, and this is taking all the space available and making kind of hard to move around.
It s like being on a cabin in ferry if i may say.
Hana is really caring even we were not able to meet her she was able to fix some little problem that we had, and was very accommodating for check-in and check-out. Recommended if you don't mind the space issue, that can be quite a problem, and if you are looking for a real Airbnb experience more than a serviced apartment.
