2 colleagues needed a possibility to sleep a few days in 1090 Vienna on a very, very short notice. I booked the flat at 5 pm. Mario (the host) responded immediately, was 15 minutes later in the flat, installed the WIFi, and around 6 p.m my colleagues started their 4 day stay there.
The flat and host are in fact that good that my two colleagues will stay there next week again.
