Pros: Clean and good location
Cons: Host unexpectedly showed up while in shower one evening without notice, hard uncomfortable beds, hard to enter both main door and door to the apartment by current keys, no central heating (gets pretty cold).
Most airbnb's I've stayed in have a booklet or paper explaining things or specific instructions for the place and surrounding area. The kitchen should come with instructions. Very different to American kitchens.
No elevator, have to bring your stuff upstairs; but, at least only one flight of stairs.
