Where do I begin? Ok, location: The location could not have been better for several reasons. For one, it is very central, whether you need to get to Piazzale Roma (for buses & trains), Saint Mark's Square, Rialto, l'Accademia, Campo Santa Margarita for some cool local hangouts near the university, etc - it's all a few minutes away on foot (and best case scenario is you get lost in any of Venice's beautiful little neighborhoods along the way). For my purposes, it was also extremely close (3 min walk) to the Archivio di Stato in Frari, so ATTN RESEARCHERS: you want this place. Oh, and I should mention it's also a few doors down from my favorite pasticceria (bakery) in Venice. Go to Tonolo, and try their bigné al cioccolato (the dark chocolate one - trust me).
The apartment itself has everything you'll need: AC, fully equipped kitchen (including espresso makers, both Nespresso & a caffettiera, which is far superior), sheets, towels, hair dryer, etc. Also, salt, pepper, sugar, espresso grounds, etc. It also has plenty of room (three diff rooms, not counting kitchen and bathroom).
Communication was a breeze. The owners are very nice and quick to respond to any questions you may have. There was even a fresh bottled water, milk, and crostatine for breakfast when I arrived.
In sum, very comfortable, and very central. Would def stay again.
