This is a big, comfortable flat in a great part of town, close to Otto Wagner's art nouveau Majolica House, the Kettenbrückengasse U-bahn station (also designed by Wagner), and the Naschmarkt. The bohemian/middle-class neighborhood (Margareten, district 5) has cafes, small grocers, restaurants, and flower shops.
The flat is quiet, peaceful, and perfect for a group of friends/family. It is very clean with good quality, fresh linens and a variety of other useful amenities: dishwasher, washing machine, and high speed WiFi. Our host, Martha, was very responsive and quick in providing a few extra items. The check-in/check-out process was very easy. I highly recommend this lovely place.
