I've found the easiest place to find hotels that guarantee connecting family rooms is through Booking.com. Search for 2 adults, 2 kids, 1 room, and then scan through the results for family connecting rooms. We're going to Madrid in June and staying at the Hotel Regina. The Hotel Vincci and Melia chains tend to offer family connecting rooms, and you can also search for connecting rooms on Hilton.

Westin Palace I think does. It is a beautiful hotel and great location. The cupola is stunning.

Most hotels will not be connecting rooms. You may be able to request them next to each other in the hallway though.

In Spain, I like to use NH hotels or AC hotels there are many of those. AC hotels are affiliated with Marriott Bonvoy.

Hotel Liabeny. Two adjoining rooms and great location (although it was loud at night due to the location but I sleep with white noise so I was fine).

Hilton allows you to filter for hotels with connecting rooms from its website. I quickly looked up Madrid and saw six options ranging from 150-500 Euros per room/ per night.

Does anyone have a recommendation for a Madrid hotel in a good location that has connecting rooms, one for spouse and me and one for our teens. A suite would be fine, too, as along as there is an actual bed in both oarts, not 1 bed and a sleeper sofa. I’m looking for something nice but not Ritz Carlton level.

I appreciate any leads.
