We have spent 4 nights at Air of Art apartment. We were group of 4 adults (a couple with 2 friends). We have found the place very clean, bright and well equipped for our stay, however it is ideal for 2 people . Efficient air conditioning was keeping the apartment nicely cool during the July heat in Bologna.
Instruction provided by host how to find the place with the car were good, however our rented car navigation system still tried to get us to the communicated destination via a limited traffic zone. Be careful. Parking is nearby and is secured. The place is easy walking distance to the Bologna's tourist attractions.
Communication with the host was excellent. Mattia was waiting for us and kindly helped carrying a coupe of big bags up the stairs. He also provided us with some useful information about Bologna.
The place is very charming, with the nice balcony, very well suited for the mild(er) days. Neighborhood is a traditional Italian with close neighbors, and can be a bit noisy sometimes, however we did not have problems.
We would not hesitate to come again.
