We had a wonderful time at Irine's flat! It is a cozy, clean, lovely decorated and fell-like-home place.
It has a small kitchen well equipped, even with some emergency food. The shower is great as well as the big bed and bed sheets. It is located in a building that is being renovated (May 2017), so don't expect a good look on that. As it is on the first floor, sometimes we could hear the neighbors in specific hours, but really nothing to worry about (and we are picky about noises). The check in and out was easy even though we didn't meet Irine in person, her friend was there. Everybody already said it, but the metro is really in front of the door and it makes the life in Vienna so easy! It is also located at a pedestrian street with everything one might need: supermarkets, restaurants, fast food, laundromat, stores, etc. Totally recommend this place for a short or long stay for two people :)
See you around Irine!
