Hotel Sercotel Carlos III

Hotel Sercotel Carlos III

10/10 Excellent
"We liked everything in this hotel, it was a very pleasant stay. Comfortable beds, spacious room, sparkling clean. Very pleasant staff, cheap parking nearby. We normally don't take hotel breakfasts, but were tired and took one to try. It was the right decision: fresh, tasty food, balanced choices. Overall excellent experience. "
