My family and I just stayed at the Hostal Acapulco for 3 nights this past week and I thought I would pass along our experiences for those thinking of staying there in the near future.
I would agree with past posts that the staff is very nice and helpful. The location on the Plaza del Carmen, very close to the Puerta del Sol is also fabulous. It is very clean and there is free internet access in the main room. Those are the good things...and they are very good.
Unfortunately because of our experience there, we would not return. There was construction right out our door, on the balcony (so no view of the Plaza), and the construction work including the banging made it impossible to take a siesta or to sleep later than 8 am.
The tv was programmed so that the volume would not be too loud, so it was difficult to hear it with the noises.
The most unfortunate part was that the aire conditioning was not working in our room, and although we had 2 fans, it was very warm and uncomfortable at night. They were unable to give us another room, although I had booked our room over 2 months ago. When we left, they gave us a 15% discount on the room, so our room for 3 cost us 186 Euros for 3 nights.
Hope this helps others plan accordingly.
