This is a good value, especially for someone just arriving by, or leaving early by train. It's very near the station and check in is done using a lockbox so you can get in right away (Eduardo provides instructions with pictures that are crystal clear).
The apartment is basic, as you'd expect in this price range. But it's comfortable enough and it's got what you need. There's a microwave, a small fridge (Eduardo left a couple Estrallas in there for me, and a bottle of water), a nespresso maker (Eduardo provided some pods), a few cups, a bit of cutlery and towels.
I thought the bed was comfy, and everything was clean. There is AC, but, during my stay anyway, it wasn't very powerful so I turned it off and opened the windows. There was also a high powered fan, though, and that worked fine for me, even in August.
It's a very quick walk to the train station from the apartment. You're not in the heart of the tourist area, but, given Girona isn't that big, you're pretty close to everything anyway (maybe 10-15 min walk to the old town).
Eduardo was very responsive and even came quickly over to help me when I was having trouble figuring something out.
Not a luxury stay, but for the price it's a good value, and very convenient.
