During our stay, June 08-10 temps in San Francisco were a record 100+ degrees uncommon for this region and it was HOT! especially the inside of the unit. It was a warm 86+ degrees during the day and into the late evening. The unit did not have air conditioning nor any ceiling fans, so sleeping at night was not comfortable and certainly not fun especially if your used to having A/C, we had to open up all of the windows and back door to try to get some kind of circulation, even the renters in the next unit did the same, but we had no luck it was just so hot. Also the areas was not a bad area but there were some shady folks out at night so leaving the windows open was iffy but we had no choice since we just wanted the unit to cool down a bit. We turned the built-in HVAC fan on to see if that would help but it still didn't. I don't want to take away from this units other great aspects because everything else was awesome we had no issues but maybe it should be listed in the description that there is no A/C in the units. As this could be of importance to other renters, especially for those who are traveling during those summer days when temps will sneak up on you. I did ask Darren after check-out if the unit had A/C but never heard back?
