Hello, do you have any recommended websites (other than airbnb) to search lodging options in Cinque Terre?

I would use Booking.com for research and then book directly with the hotel. In the past, before the pandemic, I had good experiences with Booking. But these days I'd want to deal directly with the hotel (not a third party) in the event I needed or was forced to cancel/rebook.

There are more hotels in Monterosso and Vernazza... I like Manarola for its quieter atmosphere (Hotel Marina Piccola), but we have also stayed at La Torretta. Frommer's has a short list...

We stayed here 6 or 7 years ago. Very charming.
