Chris' apartment is very conveniently situated just 20 mins walk from the main train station and very close to a tram stop for the city centre which is anyway only a 20 min walk. The apartment was very peaceful when we were staying. Chris welcomed us at the property at the agreed time and explained necessary things. The bed is extremely comfortable and the apartment has all the things we required for our self-catering stay. And it was definitely a very good price for a stay so close to Vienna city centre.
