It’s admittedly been some years (pre-pandemic) at this point, but the Airbnb’s I had in Paris are what kind of sold me on Airbnb in Europe. Very nice experiences. Either great spaces, great locations, or great hosts. Hotels in Paris are expensive, good ones more so. Still, the landscape has definitely changed and the monetary value of Airbnb vs hotels hasn’t held. That’s the number one complaint these days, that by the time you factor in the fees it can be almost equal. Money aside, I always enjoyed the way having your own flat made you feel like a real part of the neighborhood. Having “your own” corner cafe in the Marais versus a grand place on St. Germain is a different experience, and staying in a neighborhood just outside the city center is a nice trade off of atmosphere and price that hotels may not provide.
I’ll note that I was recently searching London for 3 beds/bedrooms and this seems to be a problematic number to accommodate. I found almost nothing for three people that did not have one of us sleeping on a couch. The next level up was of course terrifically expensive.
