We had a great stay at Konstantin's apartment. Although a bit difficult to find, it was in a great location (don't look solely on Google Maps to find the apartment, but look for the actual number 13 on the building) and had everything we needed. We didn't understand how to use the keys, but Konstantin was really accommodating and helped us. There are two keys: one into the building from the street, and one to the apartment itself. We struggled with the door from the street; do not use the key to unlock the door itself, but rather turn it in the lock on the panel board of doorbells to buzz yourself in. The sink in the shower room needs to be fixed, but did not inhibit our ability to shower at all. The apartment felt modern yet old, and has absolutely everything we needed! Would highly recommend. Also, the AirBnB advertisement say this apartment is one of the only ones in the area with a dryer. We thought this meant a dryer to follow after a washer, but I think it actually just means a hairdryer, which a lot of AirBnBs have. Not a problem at all, but surprised us a bit! Finally, there's an elevator to the top floor of the building, but from there you go up about 20-30 steps to get to the apartment. Just so that's clear!
