I spent 3 nights in Andreas apartment. I would conclude: great location and OK if on a budget; you really get what you pay for. Feels like a hostel without the staff rather than an Airbnb.
Location: 10/10. Central with a direct metro to all the key city sights. Nice neighbourhood.
Apartment, amenities: 3/10. 4 other rooms, a kitchen, and 2 shared bathrooms. Bathrooms have mould on the walls, although clean toilets. There are queues and no hot water (especially if someone is in the kitchen). The kitchen is chaotic and awkward to use with other guests. Depends who is there - eg one other guest refused to leave the kitchen each day and it felt as though we were intruding on his private space…
Sleep: 4/10. The bed is hard but comfortable with 6 pillows available. The room is really hot, even with good use of the shutters. It faces an inner courtyard shared by many other apartments, so it is loud. You can also also hear the other guests in their rooms (talking, films etc).
Cleanliness: 2/10. The floor is very dirty, your feet go black. In the kitchen, you rely on the goodwill of other guests to clean their used pans/plates/sides etc. The bathroom showers are dirty and walls mouldy. However, the toilets and sinks are clean.
Host: 2/10. We didn’t meet Andrea, but a concierge, who opened the doors and gave us a key and then wasn’t seen again. It felt like a hostel but without staff.
