I stayed in this hotel for 7 days and it was absolutely marvelous. The location is exceptional. It is close to the cathedral, plazas, restaurants, cafes, and museums. The staff was wonderfully friendly and accomodating. For example, I had to catch a flight at 6:30AM, and they packed me a breakfast and called me a taxi since I would miss the complimentary hotel breakfast that started at 8AM. The staff also is multilingual and is fluent with English. They gave me very helpful tips on things to do and places to eat. The room was very clean, spacious, and well kept. I enjoyed the simple breakfast which included four varieties of bread, muffins, cheese, cold cuts, a delicious tomato spread, yogurt, fruits, cereals, jams, coffee, 3 different juices, and milk. Overall, I enjoyed my stay at Casa de las Mercedes. I would recommend this place to others, and I would stay here again.
