The Casona plaza is at a great location near the plaza de armas and the main strip of restaurants and shops in the center of Puno. The hotel is nice and well maintained. The room we had was huge with a seating area, table and a king sized bed. The bathroom was large, too, and we had plenty of warm water. Breakfast was elaborate with different kinds of breads, jams, meat, cheeses, fruits and fruit juices and you could get your eggs as you liked. Overall, it would have made for an excellent stay if it wouldn't have been for the loud street noise and party/music until 3am in the morning. The windows are very thin and poorly insulated. We essentially didn't get any sleep on Friday and Saturday night, which was extremely disappointing. Sunday night was as if somebody turned a switch. Super quiet and we finally got a good night's sleep. Stay there during the week on workdays, but unless you are out there partying, don't even bother to stay there over the weekend unless you don't care about getting any sleep.
