We are an extended family of 9 taking a trip and hoping to find an apartment or two, if they are in the same building, for a ten day trip. Does anybody have any suggestions about where to look?
In addition to obvious places like Airbnb and VRBO, you can check booking.com. There might be other, better options for such a large group, but I don't know what they are.
Booking.com has a feature where you can put in the number of adults, number of children (and ages), then the number of rooms wanted.
It will provide options from houses, to multiple rooms or apartments in the same property, including hotels.
