We loved staying at Ania's place! The location was very convenient and was within walking distance of everything we wanted to visit. The place was super clean too, with a great balcony. Ania was diligent with checking that we were okay.
Not for this listing specifically, but for building in general: check w/ concierge about the elevator, as our floor button was broken for one of the elevators. (we learned that after a few packed round-trips), but this didn't detract from our stay.
I would definitely recommend this if you're looking to tour around DT.
