We enjoyed our stay with Arian.
Check-in was very easy. I messaged Arian through the Airbnb app on the day of our arrival and he messaged me the code to the key lock box.
The apartment itself was clean and well decorated - the pictures are accurate.
One downside is that sound carries in the building. On a few occassions we could hear people walking/running around above us. However, other occupants were respectful and the sound was not disruptive and did not last long.
The main downside of the apartment is the bed. The bed frame and mattress are very squeaky and the headboard is only attached the bed at the bottom (near the legs) so it wobbles a lot, even if you are just gently sitting down on the bed. Overall, the bed frame seemed quite bit cheap.
Overall, I did enjoy my stay here and would stay again. The apartment was clean and comfortable and Arian was reliable.
