We booked this in December, and planned for the heavy vacation season. But houses to rent were nonexistent 8 months ago.Beach cottages tend to be furnished with second hand or old stuff. Unless you're made of money you're not going to put brand new stuff in somewhere you're only going to use part of the year. An old stove like that is fine for cooking eggs on at breakfast, which is probably all it will get used for. Supper will probably be done on the barbecue and I doubt the wife is going to be doing any baking on vacation.
You should also have noticed that the chairs are worn with the paint rubbed off in places. It's probably old furniture repainted white to cover up the wear and make it match. Again though, Steamy didn't fly half way across a continent in order to be spending a lot of time indoors, so it's not a problem.
There are loads of beach cottages in my area (southwestern Ontario), but they were all booked up for the summer at least 6 months ago by people who knew they weren't going abroad on vacation this year. If it's like that in the US then Steamy should consider himself lucky to get anything that was reasonably habitable.
