The flat is very centrally located in the Bari Vell quarter, just a few steps underneath the cathedral and in a street with lots of shops and restaurants. I would definitely recommend this flat for a short city trip for 1 or 2 people.
In general the flat is very well furnished. Most furniture looks new and you can tell, the flat has recently been freshly painted. During my stay the weather in Girona was quite cold and wet, so the flat also was relatively cold. There are some electrical heaters in the flat that helped, but the stone tiles on the floor don't really warm up. The kitchen is equipped with all you need to prepare a breakfast or do some basic cooking. There is also a microwave and a stove, but no oven.
Communication with the host was really good ahead of my booking. During my stay I had two questions, which took a bit longer to get an answer to (up to 48 hours), but in the end the issues were solved.
Since the flat is in the old city center, you have to be aware, that it is quite dark due to the narrow alleys in the Bari Vell (no direct sunlight). Also many people walk along this alley in the evening, so I would not recommend it to people with a very sensitive sleep. For those who want to be in the center of the city and close to all the famous sights, restaurants and shops, the location is definitely perfect.
