Maria Teresa's place was very nice. I stayed at her place for a couple of night with a friend. The place is about a 10 minute walk from Piazza Maggiore so very close t the centre.
Maria Teresa was very friendly and helpful. She was very flexible with check/check out times and was always available and was eager to help with giving advice on what to do in and around of Bologna! Bedding was refreshed every day and there was always cold water available during the very hot days we stayed there.
Maybe one small note is that Maria Teresa's place is right next to one of the bigger rounds in Bologna, and it can be a bit noisy outside at night.
