Check-in was easy and flexible and we were greeted on time at the door. It's in a great part of town, close to the Central Train station which made travelling to and from the airport, as well as for day trips very convenient. The apartment is located on the second floor and in a building which is off the street and looks out onto a very large, attractive courtyard shared by three other buildings. Extremely quiet for sleeping - no traffic noise, but it is worth noting that the balcony sits above a children's play area and scooter run. At times, particularly at the weekend, it can be quite noisy amplified by the acoustics of the courtyard up until 7:30 in the evening.
There are several great spots within walking distance such as Cafe Goldegg for breakfast, Sixta restaurant (amazing food and service), Walviertier restaurant (with a lovely garden if you are lucky to have the weather for it), Pub Klemo (extensive wines & spirits and friendly staff) and Kaffeefabrik gourmet coffee. Peter provides both a coffee maker and capsules, but also a filter coffee maker and we purchased some delicious coffee to make at the flat. There is also a SPAR Gourmet shop (convenience store) across the street which is very handy. As well there is a Hofer (Aldi) a few minutes away.
My husband and I very much enjoyed staying at Peter's flat. It was exactly as described, stylish, very clean and nice amenities. If we have a chance to return to Vienna, we hope to stay here.
