Overall the experience was great. Niccolo's friend Carolina met up with us at the train station. She was really friendly and spoke great English. She was about 10-15 minutes late meeting us which made us worry whether we were at the correct meeting place and time. The apartment was very clean and had all the essential amenities (Internet, A/C, linens, towels, etc.) We were disappointed that the washer was broken and we were only told an hour after we checked in. We were relying on the washer and was one of the reasons we chose this Airbnb.
Communication with Niccolo and Carolina is great. We were having difficulty with the window and they responded to our e-mails promptly. The location of the apartment is amazing - it is close walking distance to everything (only 10 mins from the main train station). Be mindful that it is on a street with bars and restaurants so it was loud at night till around 3 AM (earplugs helps!).
We would recommend this apartment!
