House Sitter in Sioux Falls, South Dakota

I am looking for a house-sitting job in September, dates somewhat flexible. My 2 sisters and I have a reunion every fall, usually taking turns at each other's homes. However, this year (2017) we need to meet in a central location, which would be Sioux Falls. We are 64, 71 and 75 years old and are clean, in excellent health, do not smoke, do not party. We are mainly looking for a place where we can just hang out and do puzzles and play cards, have access to shopping. We do not need 3 separate bedrooms, but 2 would be nice. However, if only 1 bedroom would be available, we could bring along a blow-up bed for one of us, and the other 2 could share the bed. We would take excellent care of your home and treat it as if it were our own, being respectful of your belongings. We would rather not care for pets, but we wouldn't rule that out completely. We would consider a cat, but probably not dogs. I know we would do a great job for you, while being able to be together with each other as sisters. Please consider us. Thanks!
