We got the apartment that sleeps 4. What we did not know is that the apartments are no where near the office. I had to drag my luggage from the train station to the office, get my keys, then drag my luggage back in the direction of the train station then walk another 10-15 minutes to this tiny alley that's 4 maybe 3 feet wide. The apartment is 'charming' and there was an attempt to update it with new toilets, etc... There's a kitchen that we didn't use, I doubt you could cook a meal there. On the plus side, it's really near to the ghetto and the S.Marcuola vaporetto stop (water bus line 1, very useful). It's also a short walk to the Guglie stop (lines 4.1, 4.2, 5.1, 5.2) which is good for heading out to Murano or if you just wanted to ride around Venice.
