Casa Alma is an amazing apartment!
The location is wonderful - We were just a 15 minute walk to San Marco square and other main sites. The neighborhood was quiet and peaceful. Easy access from the main airport via the Arsenale stop.
Great communication with the owner - Marika communicated with us from the very beginning, offering clear directions (with photos) and suggestions on how to reach the apartment form the airport. We did not meet her personally, as her mother greeted us and did the check-in. But, Marika left flowers, wine, and sparkling water to help us celebrate our wedding anniversary. Her mum showed us all around the apartment and gave great suggestions for restaurants and off-the-beaten-path sights (go see the old hospital and eat at Jonny's!!). Our plane was almost 4 hours late, but we communicated via text messages, and her mum waited patiently and was so sweet when we finally arrived.
Beautiful apartment - The apartment was clean and looked just like the pictures. We felt right at home. The neighbors were not around, so the place was very quiet. Although the weather was warm, we felt very comfortable inside.

I would not hesitate to go back to Casa Alma!! It was simply amazing!
