My son and I stayed here for a week while we were hunting for his own apartment (he is moving to Palma).

Mercedes is just fantastic! As others have noted, she does not speak much English, and even though my Spanish is pretty bad, we managed to communicate just fine using Google Translate when necessary. Her family often dropped by, including her super-cute grandson Pepito.

The facilities are very nice--just as advertised. I appreciated the air conditioning, which is not especially common in Palma. The location is pretty ideal. Easy walk to Plaza España, Plaza Mayor, the cathedral, etc. Many great cafes, restaurants, bars and shops within 3-4 blocks. We loved La Tapa Andaluza, just around the corner.

Only slight negative I can think of is that the wireless Internet was a little slow at times--mostly just during peak hours in the evening. Otherwise, everything was just great! I plan to stay here with my wife when we come back to visit our son in a few months.
