The location is great because it's not full of tourists and has a ton of interesting shops and places to eat. Yet you're within walking distance of tourist attractions. And you're close to public transportation, including 2 metro stops.
The apartment itself was clean and had all the basics. As some other reviews have said, it does not get a lot of natural light. The windows face a stairway that is open to the sky, but the sky is several stories above the apartment. Also the bed is very firm, so if you prefer a soft bed, not a good choice for you.
Elsa was very helpful with answering questions and providing information.
