The agency FAVILLE TOURS was the lousiest agency I've ever encountered! Once they had your deposit, they couldn't care less about keeping you informed. I had to pester them continuously with emails and phone calls to just get an answer from them. I will NEVER book through this agency again. More is the pity since the apartment Ca'Vivaldi was really a very nice place and excellent for our needs: four friends who wanted to visit the Biennale in Venice.
