We rented Jules place for 3 nights and could only stay 1 night due to the air conditioning not working. The first night was so hot, we were miserable all night, having to leave the windows open all night to try and get a breeze. I texted Jules the next morning and he said he would send someone to repair the air conditioning unit while we were gone.
I could tell someone had been there when we got back late that afternoon because the shower was dirty, where they had washed the filters out and left a mess. The unit worked well for about 30 minutes then got hot again. It's now 7:00pm and I know that he won't be able to get a repairman to come back that time of the day. We had to make the decision to move to a hotel, because we wouldn't be able to spend another night in the heat. This was very inconvenient and ended up costing money that we hadn't planned. Jules sent me a text offering to settle for about 1/3 (45.00 euros) of what he actually owed. I told him that we stayed less than 1/2 the time we reserved and felt he owed us 120 euros. He told me that I was unkind and that we didn't have the thermostat set correctly. We live in an area that has more than 100 days a year over 100 degrees fahrenheit, and I'm very familiar with how to set an air conditioner.
Jules continuously denied that anything was wrong with the air conditioner and it was my fault for not setting it properly. We left the apartment in the same condition as when we arrived.
In the end, he will get the last word.
