The appartment is small and cozy but perfect for 2 people. We stayed there 1 week and it had everything we need for our stay. The washing machine was very useful. You can also find all kinda of kitchen appliances.
As for location, this is the best possible place to discover Girona as it's just a few minutes away from all the main spots and restaurants.
Communication with the hosts was very easy and timely. They are more than friendly and are happy to help with peronal recommendations.
The only negative thing is that the street can be a bit loud so you might have issues if you are a light sleeper but who cares after a long walk on Girona's pretty old streets :)
