We had a lovely time staying in the apartment. Sharing it with her family wasn't an issue at all, they were quiet, helpful (speak little English but this wasn't an issue) and unintrusive, even cleaning our sheets at one point and helping one of us with our laundry. The beds were comfy, the room was cool and pretty (lovely balcony, though the street is a little loud) and the shower was SO good.
Very good value for money, I heavily recommend staying here.
