The agency is very responsive and helpful, from picking us up at the airport and even getting us set up with Euro SIM cards.
The apartment is on street level on a narrow street with only a little traffic. We liked the location very much, quiet, central to the centre as well as the shore. Nice shops and brasseries nearby. The beds were very comfortable, our 6'5" son even fit in to the bunk bed. Great library of travel and art books in many languages.
The only downsides were - a smell of septic, which was mitigated by opening windows, appliances that didn't work (microwave and hair dryer). Small things at the end of the day, which we figured out pretty quickly.
