Lena's apartment is in a great location in Neubau, 2 minutes from a tram that can take you to the Museums Quarter (if you don't want to walk...), near lots of cafes and restaurants, and near a main shopping area and a subway station. You are near both chains and tasteful boutiques. It is relatively easy to get to apt. from airport. Lena showed us in and let us leave luggage as the place was being cleaned (early arrival) and also allowed us to leave suitcases after check in (late departure)--so that flexibility was highly appreciated. Apartment in older, nice apartment building feels spacious and is very pleasant, with a nice view of another old building across the street. Bathroom is new, and the two sinks a nice bonus. Plenty of hot water. Toilet in a separate room-quirky! Spacious kitchen too. Building has elevator, good for heavy luggage... the TV is quite small, so it may not be the best for binging on cold nights, but there was BBC World in English, some consolation to all the dubbed programs... In summary, I highly recommend this apartment for a Vienna getaway.
P.S. an unusual Christmas market nearby is recommended: Spittelberg Markt, which is actually located along small streets in the neighborhood, and you walk up and down the streets along the stands with crafts and foods and most popular, stands of PUNSCH, hot cider, in a huge variety of flavors, also non-alcoholic (kinder-punsch). Fun!!!
