We have stayed at the duplex offered by CanSavella in three (two adults and a child).
CanSavella owns the whole building (there is a check-in machine in the lobby so the arrival is very convenient). This is a really nicely renovated historical building.
The location is just great - walking distance to most attractions in the old town. If you are a walker you can reach the beach in 15-20 minutes.
Both building and the apartment were really clean.
Contact with CanSavella team is extremelly good. There were missing few sheets on the day of our arrival (Sunday), we called the staff and in 15 minutes one of the staff members (Carlota) arrived and fixed all of our issues.
We highly recomend CanSavella. Next time in Palma - CanSavella will be our choice for sure.
