We stayed with Karl @ Pension VITIS.
He was a very efficient and thoughtful host and one can tell from his rooms that he puts in alot of effort in upkeeping his property. the rooms were spacious, and well maintained. we had chocolates on our bed waiting for us when we arrived. the apartment had a kitchenette and he provided coffee maker, kettle etc so that we can have free tea and coffee. Internet access at the common corridor was available 24-hrs, FOC. We could use his washing machine and dryer for a small fee (and this was really useful considering that we were mid-way into our 2 week vacation when we reached vienna)
we could have breakfast either in our room or @ the terrace and since the weather was quite fine, we gladly chose the terrace :) it was a nice touch.
my 2 complaints about his place --
(1) it is situated in a residential part of vienna and is very quiet -- there isn't anything to see or do. On the first day we arrived, as we got there quite late, close to 7pm, we decided not to venture into vienna city and to eat around the B&B. there really isn't much choice although there is a mall located near the B&B .... we ended up in KFC.
(2) it's fair walk from the nearest metro station (about 10 minutes at least). When we start the day, it's fine, cos we are sill fresh and energetic! but when we are coming home after a long day out, the walk can seem very long! but of course, there's the bus stop which is nearer. but there's only one bus from the city centre so, it really depends on where we end up in the city, if we want to catch the bus. i much prefer the bus, cos it's less walking involved!
Will i stay @ Pension VITIS again? Likely. Although I may want to try to find something nearer/in the city. (only thing is the parking, can be expensive in the city!) And since we are now familiar with the public transport, i may very well choose to stay further out :)
