Mathilde's place is very unique, and it is in a great area about 3 minute work to a market, bakery and restaurants. The check in process was seamless, but once we got into the apartment it smelled at someone mopped the floor with stale water, and the pillows and bedding smelled like when you live wet clothes in the drier without drying. So I took all the pillow cases and hand wash them and air dried them using the many fans in the apartment. The cleaning service leaves the sheets drying, so when the drier ended I went to see if they were dried and they were not. I cleaned the lint trap that had over an inch of lint, maybe that was the reason they were not completely drying. So we went on our way the next morning and when we returned to the apartment this stale water smell was still there, so I started to look in every closet to see if we can find where this smell was coming from and we found in the bathroom closet a bucket and the mop that they use to clean with dirty water, I cleaned the mop and the bucket. The rest of the stay was fine. I did let Mathilde know what was happening because she might not have known what the cleaning service was doing. She was very receptive and stated that she was going to use this information to improve.
