We can't recommend this apartment enough! We spent 7 days there recently. Christiana was welcoming, flexible, and arranged for an unattended check-in, although we ended up arriving in time to meet her. The apartment is incredibly spacious! Two bathrooms (one full, one 1/2) were appreciated as we often wanted to rush out in the morning. We ate breakfast in, and had intended to cook a night or two, but it wasn't necessary. The food prices were reasonable, and the neighborhood is full of wonderful restaurants. Christiana gave us great local recommendations for restaurants and markets. The UBahn is a 10 minute walk, and the tram is right outside the door. Because the apartment is on the courtyard, it is quiet, even though the building itself is in the midst of everything. The Naaschmarket was a 20 minute walk; the Mariahilfer shopping street was very close. We had assumed we'd have to travel a bit to get into the heart of Old Town, but the UBahn and the tram made it easy. We used Uber to get to the train station, and it was only $12. We recommend the lasagna at I Terroni, the Vietnamese, Austrian and Il Mare pizzeria restaurants on Zieglerstrasse. The Berliner Doner on the corner was incredibly cheap, fresh and tasty. The apartment was spacious, filled with light, with a very comfortable bed. The full bathroom was wonderfully appointed. We used the washer a few times during the week, and that was a definite plus. This apartment experience was an incredible value, with a charming, well-organized and welcoming hostess. We recommend it without reservation.
