We decided to stay at Camila's place based on all of the wonderful reviews. And most of it is true - it is a cute, centrally located, clean apartment. However, because the weather during most of our stay was exceptionally hot, we didn't care how cute it was - we just wanted to not overheat and be able to sleep. We'd seen the note on her listing: "The house has an air conditioning system in all rooms. We have it programmed so that the whole house has a pleasant temperature regardless of the outside temperature." (By the way, the controller is in a locked box, so there is no way to change the temperature without a key.) BUT it was 106°F / 41.1°C outside on the day we arrived! That night we messaged her that the AC wasn't keeping up with the extreme heat, and asked if she had any fans we could use. It took a second message and 17 hours later for her to finally respond that the AC is kept at 75.2°F / 24°C and can't be modified - "so sorry" - but no response to my question if she had any fans. The following day was 104°F / 40°C outside. In the middle of that night, as we were literally sweating in our sleep (well, we weren't actually sleeping because we were so hot) we checked the weather outside and it was 79°F / 26.1°C. We decided to open the windows to see if we could get it to cool down, and it was at that moment very obviously much cooler outside than inside, despite Camila saying that the AC is set to 75.2°F / 24°C. Having the open windows did help the inside temperature for a short while, but the noise and cigarette smoke right outside make it unpleasant to keep the windows open for more than 20 minutes or so. I sent another message asking for fans, as she hadn't answered that question in my previous message. More than 27 hours later she responded that she didn't have any fans and she would have her friend check the AC the next day - THE DAY WE WERE TO CHECK OUT! This seemed like such a simple problem to solve, and unfortunately really affected our time in Madrid because we were so sleep deprived. We ultimately had to spend over $100 on two fans that we left there. Hopefully Camila leaves them in her apartment for the next people who are stuck there in a heat wave.
One other much smaller issue is that there were 7 of us, but she only left us 6 bath towels. I never said anything because didn't want to come off as demanding, and the air temperature was a much bigger issue. My husband ended up using a hand towel to dry off after the shower.
