I stayed in the Holistico Hostal in June 2013 with two other friends and it felt like home. The staff was the nicest we have met on our trip, the owner Sergio is awesome and we loved the breakfast! Every night Sergio planned some surprises for his guests, the room was so clean, that we could fall in our beds without cleanig anything before.
The terrace has a wonderful view on the vulcano.
In total: The Holistico Hostal is the best choice for your stay in Antigua!
