Lucia's place was exactly as described. You can reach San Marco square by walking in about 15 minutes. We did not have any problems at the Check-in, Lucia had informed us about all the details beforehand. It was very enjoyable to drink coffee in the morning with the view of the canal. Since we went in the winter season, the air conditioning in the room was sufficient for heating. I would definitely recommend it to anyone considering staying. It was a great Venetian experience for us. We did not encounter any problems, it was a very pleasant and peaceful experience.
