Affordable and really well located room. Right next to U6 and trams 6 and 18. Walking distance to Mariahilfer, U3 and U4 and Westbahnhof. Schönbrunn is 2 stations or a good walk away. All the services you may need are nearby. The apartment is alright, kitchen, laundry, showers work fine and Dominik is very communicative. On-site daily.
One complaint (even though I'm still putting 5 stars for the overall convenience and price) is that the mattress and bedding aren't the most comfortable, they could use a little upgrade but other than that, it's great.
