I have stayed at the Europa, it is a decent hotel. Nothing special but the staff was very friendly and accommodating, I never needed anything for very long. Brought all my bags up to my room and down when I checked out, brought breakfast to the room free as well. No frills at $280 per week booked online.
The best so far has to be El Palacio, very nice place and my room was fantastic. Service great, and no problems. Also, very quiet.
Next time I will stay at the Hotel en El Conde, great place and you can't beat the location either. The cafe is awesome too......
