The single most important plus point about this apartment is the location. Not only is it walking distance from most places you'd want to visit, it's super close to multiple metro stations in case you want to visit the farther neighborhoods. There are enough supermarkets, restaurants and bars close by too.
The apartment is compact and ideal for two. I would recommend going with someone you don't mind staying in such a crunched space with. Also, if you're very tall or big built, the bathroom may seem a little too small.
For me the main challenge was that I had to climb four floors with my giant suitcase, but to be fair they had indicated that in their description.
All in all, very happy with the property.
