I used TripAdvisor extensively when doing research on hotels for my European vacation. Since I found the reviews so helpful, my wife and I agreed we should write our own reviews of the hotels we stayed at in Europe after we got back.

My wife wrote the reviews and I posted them. You can find them here:

Hotel Le Pigonnet, Aix-en-Provence, France

Grand Hotel Miramare, Santa Margherita Ligure, Italy

Villa La Vedetta, Florence, Italy

Locanda Sant'Agostin, Venice, Italy
