It was a pleasure to stay in Grand Hotel Baglioni apartments. The building and the apartments are fully restored with high quality, the location is very good (peaceful area just 15 min walk from Duomo), the cleaning service was perfect and the check in also went well.
The only point that I must mention is the lack of supplies in the apartment (napkins, sponge to wash the dishes, conditioner, salt, olive oil, among others). The hairdryer also could be better since is a low power appliance.
I recommend this accommodation, you will not be disappointed.
