The apartment is very well located being on the same U Bahn (city train) from the international bus station (Erdberg) and the city main sites. It’s a very easy 5 - 10 minute walk from the station to the apartment. Check in is well communicated and done via a lock box. The apartment upon arrival was very clean and a welcoming bottle of wine was left on the table. The street is very quiet so you won’t have problems sleeping. I would recommend staying here if you want to be close to everything but just slightly away from the crowds. It’s just a handful (if not less) metro stops to escape to your home away from home.
