@Inna22No we cannot make the window between bookings any longer without losing a full night -- which often results in a full weekend -- of bookings. We already ask people to check out at 11am and most guests find that difficult. We already don't allow check in before 3pm -- which is later than many guests want. We have one small storage closet for luggage but that can only be used by one guest/group at a time (and there is physically no space for more storage). We need four hours to do a regular cleaning for our 3 bedroom, 2 bath, full kitchen bnb. If we added another 4 hours to make it 8 hours between bookings, we would just have to block another night. Not feasible.
LOL -- yes, most people who don't live in NYC have the mis-impression that it's fast, modern, you can get anything you want anytime -- that "city that never sleeps" myth. That is the opposite of reality. NYC is like a third world country. Seriously. Except that most of the 1%-ers in the country live here too. But they are not bnb hosts and they pay extraordinary amounts for everything that you and I could not possibly consider. NYC is the land of the Haves and the Have Nots.
To illustrate this environment, our housekeeper needs to take one day off, a Sunday. I have spent hours calling all over town to find a housekeeper to come in just for a regular cleaning. We cannot afford the ones that charge $100/hour -- those are for 1%-ers. The ones that charge a third of that are within our budget and fit into the cleaning fee we charge. Emergency fast cleaning? Ha! I've been working on this for 10 days so far. Nothing. Today, I spoke with someone at a larger cleaning service where they claim to have over 80 housekeepers employed. They told me that they sent out a request to "all" of them but "no one wants to work on a Sunday." Unbelievable. I have disabilities so it is difficult for me to just do it myself -- but I will probably have to try unless I can magically find someone. Emergency Cleaning? That's a fantasy in NYC. You wouldn't believe how difficult things are here unless you've lived here a couple of years. You just have no idea. Oh sure if I could pay $1,000 I could probably get emergency cleaning. Not going to happen. I can't get someone on a Sunday with two weeks notice. And market prices are so low here that we cannot afford to block nights between bookings in case we need extra cleaning. No way. The economics of that do not work here.
PS -- If you google housecleaning services that service Brooklyn, you'll find some. But they are not all valid. For example, just this past week, I sent three days corresponding with a firm found on Google. They have 50 5-star reviews. Great, right? Wrong. As a wise friend pointed out, no one has that many 5 star reviews without even one review even one star lower. Anyway, I asked all my questions and got a nice price and lots of "yes we can do that." Then, I asked meaty questions like "What is your method of payment; How can we confirm for Sunday March 14; What is the first name of the person who will be coming." Guess what the answer was? "Yes." That's it, "Yes." Fake company. Probably a shell for something illegal. There is a lot of that in NYC. Like in the movies. I lived in Michigan for the first 30 years of my life and I never would have imagined that a city is really like this. It is.
