We enjoyed our stay at the Tilajari hotel! The property is nice, we saw beautiful birds, iguanas and howler monkeys all onsite! We also did horseback riding - Bryan was our guide with the horses and he was really great, very friendly and kind.
We drove into La Fortuna / Arenal each of the three days to do activities and it was a bit of a drive - about 40-50 minutes to the different activities (waterfall, hanging bridges, volcano park), so I would stay closer next time or recommend others to do so if they don’t want a far drive.
We did have a few hiccups at the property. The wifi in our room only worked if you stood directly next to the window. We called staff about it three times, as we had to work while we were there but they were unable to help/fix it. Also - at breakfast I found a piece of metal in my eggs (they said likely from a cleaning brush), the staff did apologize for this.
