This apartment's location is amazing - steps away from Piazza Maggiore and still within a pedestrian-only area around plenty of good shops and restaurants. Plus a mini-supermarket and a pharmacy are each only 1 minute away.
The apartment is very clean and efficient. One main room with kitchen along one wall, dining table, and sofa with pull-out (queen sized) bed, which was very comfortable. The bedroom also has a queen and some shelving. Bathroom includes a washing machine, which worked well (we used it a couple of times during our week-long stay; dried clothes on a rack). Nothing is overly designed, and it feels pretty spartan (not a lot of color, wall art, character in general) - but it's a clean, comfortable, and quiet place to stay.
We were a group of three, so one person was sleeping on the pull-out bed. Luckily we all liked and knew each other well, otherwise it might have felt overly cramped (trying to make coffee in the morning while someone's lying on the pull-out, for instance), but be forewarned if you need more space.
One of the best things about it was the assistance from Elia, who communicated with me through WhatsApp and was quick and helpful with every little question I had - from entry on the first day (he sent a helpful video showing exactly where to go), rebooting the wi-fi, even helping communicate with the person delivering our lost luggage to the apartment!
Highly recommended, especially if you'll be spending time in the old center of Bologna.
