We have just had a really great 4 night stay in Antonio's apartment. We found the apartment spacious, very clean & perfect for our needs. We collected the keys from the shop as directed with no problem & had no need to contact Antonio during our stay. The location is perfect for all the sights we wished to visit & all the Christmas markets. We ate out & visited some really good bars every night & always within a 10 minute walk. We will definitely stay here again when in Vienna.
