It is a nice apartment just in front of thew lovely Naschmarkt and 20 min walk from Stephansdom. It was pretty spacious for us (family of 4) with a nice living space. The furniture (mostly from IKEA) are pretty new and there are a lot of useful services you do not find everywhere, like a washing machine in the apartment. The most exciting feature for us was the availability of a Nespresso machine. On a bit less positive side, the bed in the master bedroom was not very comfortable and the apartment could have been more clean.
However our staying in Vienna was nice, the Easy Rent team was very responsive to our questions and the check-in procedure was very nice: Anna welcomed us at the entrance, gave us a lot of useful indications and made us feel home.
