This is a nice place, and it's AirBNB at its core: meeting great people. Andrija is a very kind, and very interesting, person to meet. I much enjoyed talking to him yesterday evening.
The appartment is located in a quiet street next to many great bars and and cafés around Nestroyplatz / Praterstraße. The building as such is a bit run-down, this limits my recommendation if you would be looking for some stylish place (or romantic week-end). But Andreij's apartment is bright, clean and clear.
Clear recommendation, I'm planning to be back.
