We greatly enjoyed our stay here— lots of space and quiet. The beds were extremely soft so if you like that it’ll be an amazing sleep. Kitchen has plenty of dishes and things to cook and having some breakfast items on hand was very nice. Overall I would absolutely recommend Aitor’s space!
If you park in the Parkia Arenal garage it’s a 15-20 minute walk with a lot of stairs, but if you walk first to the Carrefour Market off the San Antongo bridge you’ll see some escalators partway up the hill that will take you most of the way uphill.
