This spot is perfect - it's right in the middle of the Casco Viejo, and right outside the door are delicious restaurants, a grocery store, bakeries and more. My friend and I walked everywhere on our trip within 25 minutes.
The flat is even better than it looks in photos, and Ibana is the most accommodating host. There was a small issue right at the start of my stay, but Ibana went out of her way to make sure it was rectified. She's also warm, friendly and makes you feel very welcome and at home.
I recommend anyone stay here!
