we stayed at at Rene's apartment for 4 nights. Rene responds fast and gives great advices and tips.
The location is great, tram 49 to city center only 2 min walk (and 4 stops), metro U3 to main rail station (to Airport) 8 min walk, same as the famous Maria Hilfer St. The apartment is to the back of a vibrant street who turned into a marvelous and magical Flea Market at Friday and Saturday, and that was a pleasant surprise for us.
The apartment itself is very quiet, clean and comfy, has 1 bedroom, 1 living room, a fully equipped kitchen and separate bath and toilet rooms. Outside, on the balcony near the entrance there's a table and two chairs for the morning coffee and cigarette. Temperature inside is very cozy, and there's always hot water.
The only thing that might bother some, is the fact that the trash cans (for the building) are located in the hallway to the inner yard of the building, on the way to the apartment.
Other than that, this is a rare find in Vienna. Thank you Rene for the warm hospitality, we definitely recommend this place.
