The apartment itself is neat and nice. To come in, you'd need to use a phone app every time, so make sure your phone is charged and has internet before you go there. The location is on a side of the center, which is an OK location. It's about 5 mins walk to a nice Arena park. And it's about 20 mins walk to the center and monuments. If you arrive late in the evening (like we did) the nearest place to eat would be about 20 mins walk. Otherwise, it's a nice place, but a bit overpriced in my opinion.
And just a warning: be cautious about the items you use at the apartment as every minor thing gets accounted for. We had a situation there, but everything was resolved fine.
