An Airbnb or Kinkbnb would suffice for that use case. I don't need a kitchen with two ovens for most of the year but when I'm hosting a large party, having the option of a kitchen of that grade is nice.
And you’re exaggerating the cost too. Two ovens? Seriously have you seen a Polish Christmas dinner? Dozen people, dozen meals, one stove/oven combo. It’s normal stuff done by normal people with small flats.
