I am a late middle-aged (53), early-retired man of extreme political views (left and right) but otherwise fairly harmless. About my only definite need is for quiet late (after 11:00 pm) at night. Otherwise, coffee in the morning is nice but not essential. My wife is younger (41) but otherwise about the same minus the coffee.
Interests include history, fishing, art, food and drink, gardening, and potentially just about anything. We'd usually be trying to get out the door by 10:00 am and would be back by around 9:00 pm, depending on circumstances. We're able to leave a place as clean as we found it.
Although we speak only English and Spanish, we're comfortable exchanging elementary needs, etc by whatever means come to hand. Amenities are nice, but we can adjust to anything except the aforementioned noise, a complete lack of privacy, or serious dirt.
