On our recent two-week trip by car to the main Habsburg cities along the Danube (Vienna, Bratislava, Budapest) and the Adriatic coast (Trieste). We (a family of 4 to 6 adults from 20 to 60) got to compare places to stay (to be booked via AirBnB/ Booking.com. Between them and with typical offers from recent years. One thing in common to all the places we stayed at is that the air in AirBnB means what it says; there is no breakfast on offer. The original idea to share your hosts' home for an overnight stay has almost entirely given away to the commercial use/misuse of rooms for rent that no local lives in/ can live in on a regular, permanent basis. Some ‘hosts’ manage as many as a dozen flats. Another thing in common to all the places we stayed at; they had all improved to include (unlike before) towels, hot water heater, instant coffee, microwave and fridge.
Plus; quiet garden house suburb, convenient parking, easy access by car to city centre, rather spacious, two bedroom garden house all to oneself
Minus; shower set up, internet access
