A great stay in every way. The apartment was both clean and spacious, with comfy beds and a great shower. The building itself and the courtyard one was looking down into were gorgeous and it's in the middle of a vibrant pedestrian area full of small restaurants and bars catering to students, which are tasty, cheap and great fun!
Be advised that there are bars right outside the entrance to the building on both sides, but everyone was very friendly and respectful even when we were coming back with expensive camera gear during the middle of the party time. The location at the back of the courtyard also meant that we barely heard anything of the busy bars in the front, when we had to get up at 6 the next morning to catch our train to leave.
Overall, what's not to like? We would definitely stay here again!
