We stayed in the studio #2, which is just as described and it looks exactly like it does in the pictures. At the beginning, we were a little reluctant about staying in a room that had to share a bathroom but in all honestly we barely noticed. We never ran into anyone in the bathroom and it was always kept very clean.
Alessandro provided clear instructions for check in and check out, and he was nice enough to store our luggage for a few extra hours since our plane didn't leave until the evening. During our stay, he responded to our messages within hours which made it very easy to communicate with him.
The only "down" for us was that we messaged Alessandro with an important question 4 months before our vacation and we didn't get an answer until about 3-4 days before our arrival date. Because of this, we had to plan our activities differently than we would've if we had known the answer before.
This was however, a good experience overall.
