During the summer it can be very warm if you aren’t used to it. There is no climate control in the space. We often took cold baths to deal with the heat.
It is important to recognize that everything else was wonderful. Jonathan was available whenever we had a question or issue. He would check on us regularly to see that we were getting on ok. The location was fantastic, 10 minute walk from the Louvre. Plenty of shopping and restaurants within the surrounding area at affordable prices. We cooked a decent amount and that was nice. There are multiple groceries nearby as well. Overall our stay was excellent.
