No one came when we rang the doorbell. We called the number provided, and the woman promptly opened the door. A minor inconvenience that was easily resolved, but I recommend having a way to phone the hotel.
The value was excellent. It is about a 20-minute walk from the bus station/Plaza Espana (maybe 15 mins if you walk fast). We paid very little, and the accommodation was immaculate, although simply furnished with twin beds. Breakfast also simple, but free, and what I would expect for the price. I would stay again, but not for my entire stay. I would stay here while sightseeing and shopping in Palma, but would want a couple more relaxing days in a cozier hotel near the beach (we are a young couple), and would be willing to pay more for that. But if you just need a place to crash, this is perfect.
