Everything about the flat itself was perfect! It was clean, everything worked, and we did not run into any issues with keys or otherwise.
One word of caution is that it is a bit of a walk, both to the more central areas (25-30 min) as well as to the nearest metro station (10-15 min). This might just be something to keep in mind if you’re visiting during the hotter months. Definitely not enough to affect my rating though, as we still had an amazing time!
