We stayed at Caroline's place for 3 nights during a very hot few days in August 2020. There is no air conditioning in the apartment, but there are two fans provided. We managed ok in the heat but it was a little uncomfortable at night. The location is great though, right in the heart of the old town and within walking distance of just about every sight and square you would want to see. You can only hear noise from the street below when you are in the living room but not from the bedroom so it does not impact on sleep. The check-in and check out instructions were not communicated to us ahead of time which was a little confusing but not a big problem. Overall, a very convenient place to stay and see Bordeaux.
