We had a great stay for a month at Maria's apartment, a short 10-minute walk from Piazza Maggiore in the centre of Bologna.
The apartment is on the ground floor on a quiet side-street off Strada Maggiore, where there are cafés, grocers, restaurants, and a supermarket within a two-minute walk. There are several bus stops nearby.
The apartment itself is well-furnished, with air conditioning/heating, a washing machine, a kitchen with all necessary pans, pots, etc, smart TV, and extra towels and bedding. Hot water from the shower is from a tank in the bathroom, which holds plenty of water for two consecutive hot showers, and the water pressure is very good. We did not use the sofa bed, but it was comfortable to sit on, and it's wide enough that it should easily fit two additional people to stay overnight. The window looks out onto a leafy street with pleasant light.
Check-in was straightforward, as we were met by Camilla, who manages the apartment on Maria's behalf. Camilla made sure we had two sets of keys and lives a few streets away - though we had no problems during our stay, she made it clear we could get in touch anytime. When we checked out, Camilla was kind enough to allow us to leave our bags in the aparment until our bus, as the next guests weren't arriving until the next day.
This apartment would be well-suited to a single guest or a couple who need to stay in Bologna for a prolonged period of time. Its proximity to amenities and the centre of town make it a great base for a longer-term stay.
