I stayed in Holistico Hostel for 4 nights from 24 Nov. I had initially wanted to stay in Yellow House recommended by Lonely Planet but decided to choose Holistico Hostel as the booking process was rather straightforward via hostelworld.com.
Holistico hostel is within walking distance to the Central Park and other places in Antigua. First glance of the hostel was inviting and upon entering, the common area by the reception came with many tables and chairs and was a great place to interact with other guests. Up on the roof, the terrace was also a nice place to hang out. The view from the terrace was great and at any one time it was not very crowded. The wifi was fast and accessible in the common area as well as the terrace of the hostel.
The bunk beds in the dorms were comfortable. I was staying in 4 bed dorm room and although it was small but quiet. There is a number of shared bathrooms and they are clean with hot showers.
The owner was friendly and went around making friends with the guests. The staff were equally friendly. During my stay, one of the guests was volunteering at the hostel. The guests were a good mix of different nationalities and mingled frequently with one another. I had a late night out with some of my hostel mates playing pool and drinking at a nearby pub.
Shuttles to other parts of Guatemala can be booked via the hostel and will stop by the front every morning or afternoon. I booked a shuttle from the hostel to Panajachel.
I am really glad to have made the right choice in choosing Holistico Hostel given that there are many other great accommodations in Antigua. The hostel is popular but during my stay was not very packed as it may be the low season. I highly recommend Holistico Hostel as "The Place" to stay in Antigua which is reasonably priced, convenient and has great facilities.
