Tini & Stephans' appartment has the perfect location. Near metro stations and definitely at walking distance from the centre. The only disadvantage may be the noise from the street, but just put in some earplugs :) The place is spacious, has a lot of light and a nice 50's - but clean - look. Everything we needed was present and Tini welcomed us personally. I will definitely visit again if I would come back to Vienna!
