We were not aware that Denis and his mother would be living in the appartment during our stay. However, it was not a problem and we barely even saw them throughout the stay and they seemed like lovely people. The only small issue it posed was having to share the bathroom and sometimes have to wait when we were trying to get ready. It was very hot in the room and only had a loud fan that was not very helpful. Also, if you have a lot of or heavy luggage, I would not recommend this place: being that there are five, brutal, very narrow flights of stairs up to the apartment. The location and proximity to the center of the city, famous sites, and the metro line was nice. If you are looking for just a place to sleep at night and leave your stuff this is an okay find.
