Lets try and build a list of great hotels - either bike related or for romantic weekends away with the significant other.
I'll make a start:
My favourite hotel in the world is in Florence, Italy
http://www.torrebellosguardo.com/en/index.htm. It's just stunning for a romantic weekend away.
Florence is an amazing city, provided you dont go in July or August. The hotel is on a hill just outside the city centre, close enough to walk in if you want to, but you might prefer to get a taxi back after all the icecream.
It's far enough out of the city to be an oasis of calm and tranquility and has breathtaking views down across Florence. The hotel building itself (an old monastry) and surrounding gardens are stunning and very cool in the heat of the summer. The pool is on a terrace overlooking the whole city - close enough to look out over it all but far enough away not to hear it. The rooms are very basic, wooden shutters, not much light, very old beds and bathtubs etc, but it all seems entirely appropriate.
the only frustration was that there's no food in the evenings but they'll recommend the restaurant at the bottom of the hill - a great family-run bistro which is another amazing place!
