Save yourself the headache and book elsewhere--a nightmare experience!! First, they double charged my booking, claiming it to "my error", as if someone would book two identical hotel stays at the same time. Even though it was clearly a result of their poor technical infrastructure, they said the refund would take 3 months and I personally had to keep pushing for this to happen sooner (ended up taking ~6 weeks). Then my reservation was CANCELED, I spent DAYS trying to figure out why and they had no answer, only to say "well it was resolved eventually".. after I myself spent time on the phone with the hotel and customer service to figure it out. Had I not had an urge to call my hotel and confirm the reservation, I would have had nowhere to stay upon arrival. In conclusion, absolutely terrible experience using Presitiga.
