This is no slick businessman's hotel, but a charming, slightly strange, small hotel within easy walking distance of the heart of Bologna. The service is extremely good -- friendly and thorough. Rooms are not luxurious, but very comfortable. The layout of the hotel reflects its unusual expansion history - rooms appear in the most surprising places. Two wonderful cats roam about (Romeo and Matisse). The location is quiet and convenient and, perhaps best of all, it is within steps of two of the best restaurants in Bologna (Le Mura and Al Sangiovese). We were delighted that we chose Hotel Porta San Mamolo.
