This is an absolutely perfect location from which to explore Girona. It's just on the edge of the busiest part of the old town, so it's wonderfully quiet, but you get amazing views of the Cathedral and not too many loud tourists wandering around below. The flat itself is gorgeous and clean, with great aircon (which is important to me in Summer!) From there everything is walkable. We came on foot and it was a relief not to drag out backpacks up the hill, but it would also be very convenient for cars - much more so than attempting the gorgeous steep and narrow streets of a lot of Girona.
We've stayed in Girona repeatedly, and this is our favourite place so far. We'll be back.
