We were a group of 12, 7 in 25 rue sainte Apolline and 5 in 21 rue Blondel. I was in 25 rue. In my first night, I saw a large rat in one of the bathrooms. Later that day, my father (also in 25 rue) saw a smaller rat in his bathroom. The next day, the host came with a small crew and caught the small rat but couldn't find the large one. That second night, my girlfriend saw the large rat crawling through her towel. We were no longer comfortable in that place and the host offered to move the ones from 25 rue to another listing, 8 rue du Charolais. Once there, we noticed the heaters were not working, only the ACs. When we tried turning the heaters on, the power went out in the whole apartment. Temperatures inside were at 10°, we had to use all our warm clothes inside the apartment. The host couldn't figure out why the power was going out when turning on large appliances. To all this, I have to say the host WAS responsive and tried resolving the situation.
