This apartment worked nicely for us! Super easy checkin with lockbox for keys. No elevator access. It’s on the 2nd floor (3rd to Americans) We traveled with our infant who comfortably slept with us in the bed. It goes from wall to wall so we didn’t worry about her rolling off. The place was clean and has lots of brochures on tourist sites. The couch was big and comfy. We cooked a lot and there was sufficient cookware. There is a 2-burner stove. Next door has pretty good pizza! There is also a dishwasher. We bought detergent for future guests! Tips: First Sunday of the month almost all Wien Museums are free (not Mozart house). Karlsplatz is the biggest, but go early or you won’t get in. There’s several other good small ones. Best weiner schnitzel is Schnitzel Wirt! Enormous serving for €8! Tram O (2 blocks down from apt on Renweg) goes to the train stain. To get to Old Town, take O tram to Landstraße station and get on U4 (I think?). St. Stephans is center of Old Town. Walking to Old Town is possible, but a bit of a hike. You can buy all-inclusive public transport tickets through the OBB app. The best deal is a day pass that lasts until 1:00am that late night for €5.80. This is only available through the app. You can buy 24 hr pass from the OBB or Weiner Linien kiosks for €8. Individual ticket is €2.40. Prices are of 10/2018. We suggest taking the S train to Renweg from airport for €2.40 instead of the CAT train. Enjoy Vienna! It’s impossible to see everything in 3 days we found out!
