We spent four days in Vienna and were very happy in Maxi's place. A slow 30 min walk via Nachtmark to the opera. A few subway stops to Schönbrunn. One of vienna's oldest restaurants 10min up on the same street. Two big beds and lovely furnished. All supplies one can need. Well functioning wi-fi. Some trafic noice reach in, but nothing that bothered us. We didn't meet Maxi, but communication functionned very well via text messages and info on the city was kindly displayed on a small iPad in the hall.
