Me and my man stayed at Albert's place only for two nights but we'd like to have more! The apartment is better than on the photos and larger, I don't know why the photos shrink it) It has many pleasant details and also it has a nose host! :D Albert really care about his guests and you can see he does it sincerely and with deep pleasure. You don't have a feeling like you are "just-another-guest, ok-just-pay- me-and-leave-everything-safe". He was kind, and when we had a problem with a heater he solved it in twenty minutes, which was also possible because of his fast message reply.
The apartment has everything you need and I think it has the best Vienna location than any other on airbnb (I spent much time for examining). I'll tell you why: if you'll find a place, that is located right in the old town ii may disappoint you, because there can be the noise from bar-people or you should walk to the VIENNA RING if you want to catch a tram. From this apartment It took me 1 hour and thirty minutes to see all of must-see places in the centre on foot. But if you want for example to have a ride it will take you 5 minutes by tram to all main sightseeings, then you can walk from square to square as long as you want and than through cozy and narrow streets of centre come back to your place. It took me one day to make this route. And guess what? The tram station is right in front of your apartment because its located just ON THE RING. So you hit the bull's eye twice)

I have some places to compare with the apartment, that were also booked through airbnb but at Albert's place was very good service and many nice stuff, that were warm and welcome. I don't know why Albert has 4,5 stars instead of 5, but I'd give him six if I could!
Thank you for making our Vienna discovery so easy and memorable!
