Maria's place is well located near S. Lucia station, which is very helpful if you are traveling by train. It's also quite cheap for Venice, but still located at the city, so it's an excellent choice if you want to experience an evening in Venice.
The room is quite basic, which is fine because you may want spend your time in this lovely city and not in the four walls.
The breakfast is great!
Maria is a very cheerful and sweet person, she met us like we are her old friends.
The only minus is a wifi available from the alley, but not in the room.
