We had a pleasant stay at the Palacio Santa Marta. Because I had previously inquired via email about how to get to the hotel and parking, the arrival was straightforward, even though the hotel is located in the old town on a narrow alley.
The service was good, the room was large, and the breakfast was adequate. The location is very good as all the sights can be reached quickly on foot.
I do not give five stars because the air conditioning in the room was ineffective—it did not really cool, there were only six loungers by the pool, and it was unbearably hot in the breakfast room, especially in the area where the buffet was set up.
