I just wished my in-laws had stayed in a hotel than stay with us. I hadn’t known or expected they were coming down so soon after and then to stay with us for almost a week was uncomfortable. I usually get on with them, but I was nowhere emotionally, mentally, or physically in a place to have people staying with us for that long. Having them around all day, having to walk upstairs to our bedroom so I could nurse in privacy, having to share our only bathroom with two extra adults knowing I won’t just be two minutes in and out. Husband was even counting the days they were to leave. It was nice to have our house back after they had gone. We both felt so much better afterwards
I hear you!
After the birth of DC2 my PILs came to stay when baby was 1 week old- they stayed for a whole month!
We live in a 2 bedroom terrace house- they slept on our living room floor for the duration. I too wished that they had got a hotel or a local Air BnB- my DH told me I was mean and not welcoming!
I get on really well with them normally, they live abroad so we only see them in the context of a holiday, and they were generally helpful and thoughtful during their stay post-DC2...but I found it all way too much
We only have 1 bathroom, and sharing with another 2 adults was a bit of a challenge. I was massively constipated for the first weeks- thank you post CS meds- and a visit to the bathroom was not always a speedy one.
Alos, there was a lot of pressure on me to leave DC2 with the PILs while DH and I took some time alone together....at 3 weeks post birth, the last thing on my mind was to leave DC2 with anyone!
we had a couple hours out together in a local restaurant- we spent the whole time arguing, I just told him exactly what I thought of him, with milk leaking out of my boobs...a very LOW moment for me.
They meant well but honestly it caused so many arguments and animosity between DH and I, at a time when we shouldn't have been, to put it bluntly.
I think it all depends on your individual circumstances, and the most important thing is that you and your partner are on the same page. Me and DH were most certainly not, and over 12 months post-birth things have never quite been the same between us 
And the PILs have not yet been back to stay
gosh, after that download, I am in need of wine
