Alex and Oscar were responsive and fast when we needed things. The apartment is great for a couple, for us parents plus adult daughter, it was too small. Location is superb, walking distance to many attractions.
We had 2 major problems:
1. There is no outer ventilation for the toilets. Only ventilation for the bathroom is by a 25×25cm window connecting to the living room, covered by a painting. So, all smells from the toilet immerse the living room. When toilet in use, this is quite uncomfortable, especially in cold days. We had to plan use of the toilet and open windows to air the apartment. Alex said this is the given situation in Paris old buildings, I doubt it and don't accept it.
2. On 3rd night my daughter encountered a mouse!!! attracted to our food. Alex refunded us one night, brought repellents and offered another day refund if we decide to leave, non practical for us. We stayed but since then avoided exposed food, worried and felt not compensated enough for the situation.
