My partner and I stayed at this Airbnb for just over 2 weeks in November and had an enjoyable time! It was perfect for what we needed.
What we liked:
The apartment is bigger than expected and nicely furnished. There's a small dining table and couch, plus it's perfectly located in the center of town close to shops and food. It's only not too far from the train station, so we could easily walk 15 minutes or so to catch our departing train. Girona is notorious for having patchy internet signal, but I found this apartment had great signal and wifi too, which was important as I work from home.
Considerations:
It should be noted that the apartment is on the first floor of the building (no lift) and its also closeby to the church which rings every quarter hour and on the hour, until around midnight I think. If you're a light sleeper this may be a consideration for you. The apartment is also run by a hotel, so we picked up the keys from the hotel.
