@Nalini14 Yes, that's one of the cool things about this international forum- so many nationalities connecting. There are many terms in English that are used differently depending on what English-speaking country you are in.
I used to get confused when Aussies on this forum referred to a "bench". In North America, a bench is a long seat which several people can sit on, but in Australia it apparently means what I would call a countertop.
I was going to suggest "Studio", but I'm not sure if a studio is something that is expected to have cooking facilities. Another definition to look up. Maybe instead of "outside" it might be better described as "Detached Private Studio", as long as the kitchen situation is made clear.
I live in Mexico, but am not Mexican-was born and raised in the US, and then became a Canadian citizen. And all my grandparents were Russian Jewish immigrants to the US.
I love all the cultures represented here.
Your concern over using an official Airbnb sticker made me recall my brother and I asking our parents when we were kids, if we would go to jail if we removed the tag on the mattress that said "Do not remove under penalty of law" 🙂
