The apartment was clean and bright, with a nice balcony. Giulio was very accommodating and helpful. We didn't have any problems, but if there had been, Giulio would have been more than happy to help.
The apartment is close to Porta San Felice. It takes about 15 minutes to walk to Piazza Maggiore.
The only downside to the apartment was the thin walls. The bedroom shares a wall with the adjacent apartment, so we could hear everything the neighbors were saying. If you are particular about noise, bring earplugs.
All in all a pleasant stay. Grazie Giulio!
