The location is great, close to everything and the metro station is just in a couple min walk. You have a supermarket and a café next to the building, not to mention famous Naschmarkt (10 min away).
The apartment itself is very cozy and clean. You can feel that owners put a lot of thought and love in it, I liked the design and gorgeous plants. We were 2 of us and stayed for 5 nights and it was perfect! The communication was also good, we had a late check in and there was not any problem.
I can definitely recommend it!
