Welcome to Bologna La Grossa. You are likely here to eat, eat, and eat some more. Sonia's place is an ideal location such a trip.
Location:
It is near the University, which warrants a stroll to see all the old buildings. However, with that said, it can get a little rowdy on the sidewalk at night, but the apartment is very very quiet. So it's not a big deal at all.
It's conveniently located near the train station, about a 10-15 minute walk, which means you can easily venture to Modena and Parma for a day trip. Likewise, it is less than a 10 minute walk to the Piazza Maggiore which is a central hub for all your Bologna culinary desires. The cherry on top is that a very good gelato shop is a few doors down, so grab a toasty-nutty pistachio one right after you check in!
Last thing which is amazing about the location is that it is near real Bolognese folks. Taking a shower with the window open you might catch a whiff of Nonna's ragu sauce in the morning.

Apartment:
It is very clean and chic. Easy to get in the apartment and it has everything you need. The style is modern and looks much bigger than in the photos. Learn some Italian to use the washer/dryer (only dryer we came upon in Italy!). The bathroom was very good, the shower has great pressure and there is an abundance of hot water. Internet was fast and I experienced no problems. Overall, highly highly recommend this pad to crash after you stuff you face with tagliatelle.
Check-in:
Super easy and friendly. Paolo greeted us in person on Easter Sunday, which was very nice of him to take the time to do that (thanks again!). It was super quick and he gave us solid tips about the place and Bologna. Also presented us with a bottle of refreshing and tasty sparkling wine from his farm (wow!). So nice and friendly, highly recommend.
Overall, if you come to Bologna to walk 10 miles or climb the towers to end you day with pies and piles of pasta with ragu and crudo, this is the best place to crash and freshen up. So close to everything, tourist sites and train station. 10/10 A+++. Grazie mille!
