First, let's just get out of the way that the immediate impression of the building will have you questioning your choice. The B&B is house in a mixed-use retail/office/residential building, and you will initially wonder if you've made a HUGE mistake.
You have not!
(And I'm almost hesitant to say so, for fear that upon our return in the future they will be booked full...)
This is an absolute GEM of a property, run by Loris (the owner) and his wonderful assistant, Ambra. Simply put, they are amazing. The rooms are impeccably clean and well-appointed. We spent several nights in a 4-star hotel in Rome which fell short of La Casa sul Mare in every respect other than square footage.
A well-provisioned kitchen is available 24 hours a day, the in-room amenities are modern, the bathrooms are spotless, the bedding and towels are plush, and there are blackout shades that I'm certain would shield a nuclear blast!
Have I mentioned how wonderful the staff is?
We are disappointed that only booked one night, and in the future, regardless of our itinerary, we will certainly stay longer.
In addition to the complementary pastries, teas, coffee, espresso, and snacks there is a selection of wine, beer, and soda available. (Sparkling water on-tap? Yes, please!)
You may stay in more luxurious properties, you may stay in larger properties, but you'll be hard-pressed to locate a better property.
Ample restaurants are within a short walk, and you won't be lacking for anything.
