Boris' place was perfect for our requirements. I had business in St. Pölten, while my family (wife, baby daughter and tottler son) accompanied me. It is in close proximity to Westbahnhof for connecting where you want to go - regionally or central Vienna. Self check-in was well explained and the apartment was clean and well prepared for our requirements. The apartment is judged to be ideal for a couple wanting to get the most of the Vienna experience or for business people requiring central accommodation. However, it was perfectly fine for our family of four for our week's stay. I would again make use of this apartment or recommend it to other travellers.
