Me and 2 friends stayed in Martina's apartment for 2 nights. We agreed to meet in the apartment at 12:45-13:00 and nobody was there. Martina only gave us the number of the main door, so we didn't know the floor number. Also the main door was closed and to go inside we needed the key. We tried to call her using the number from Airbnb page and no one answered. After many attempts she finally answered the phone and told us she was not in Italy but some guy will appear to open up the door for us. After waiting enough time the guy appeared and opened the door for us.
When we finally thought that the initial incident was over, we found that the apartment had not been cleaned yet (the guy told us that the cleaning will go there in 1 hour).
As we had already lost enough time and we already had our schedule for the afternoon conditioned, we went out to visit Milan instead of waiting for the cleaning.
In the evening we came back to the apartment, it was cleaned but was not an extraordinary cleaning. It seemed that the cleaning was done in haste. There was only 1 towel for each person instead of 3 (as it was said in the page), the hand soap in the bathroom was empty..
The apartment itself was really good, just like the photos and the location was also good, near the metro station.
It is unfortunate that this has happened to us after a really good contact with Martina by Airbnb messages before the trip.
