This is in a good location, and although very small it was serviceable (although no iron, no scissors, no matches, no bedside light, no wifi). It's right on the canal, which is beautiful, but also means closed windows (or mosquitoes), and mold. Acceptable for the price.
However, I cannot recommend staying in Elena's apartments. First, she said she would meet me to give me a key, and then 30 minutes beforehand a "friend" texted to say she would meet me -- a surprise. The friend was kind, and ended up being a big help, but clearly Elena -- who lives outside of Venice -- has a series of apts she rents out for income.
Unfortunately, after dropping off my things and exploring the city for a few hours, I returned to find the key would not open the lock. I texted Elena for help. During my stay, she did not reply to a single text. I ended up having to call from a nearby restaurant (my phone worked in Venice, but calls were very expensive). After first expressing disbelief, then repeatedly asking me the "name" of the apt (?), she did eventually recognize the location and came with a locksmith -- but the entire process took several hours, and the door had to be broken in order for us to enter and Elena implied it was my fault. There was a secure outer door, and she offered me the adjoining apartment for the night, but I spent the hours of 7-10:30pm dealing with this, and then slept in an apt with a broken door, not knowing what time a locksmith would return the following day, nor when tenants would enter the adjoining apartment (I was told it was rented the next day). The following day I went out for a few hours and locked my things in the adjoining apartment so that if the locks were changed I would still be able to get my stuff (Elena, again, replied to none of my texts), and I spent an uneasy day wondering if I would be able to access the apartment later, and if people had access to the apartment where I'd left my things. I returned, simply by chance, just as the locksmith was leaving (with the keys to the new lock). I convinced him to call Elena, who eventually told him to give me the keys. The experience was unnerving, and although she apologized,Elena was clearly annoyed that she had to make a trip into Venice. Since a functional key and lock is a pretty basic requirement -- really the minimum -- I asked for one night refund (I was in Venice for less than 36 hours total, so it really cut into my visit) and she refused and in our email exchanges grew incredibly rude, calling me a "liar" and "opportunist." Had she been professional and kind from the start, it would have been fine. But overall, Elena was unfriendly, even downright hostile. I left feeling terrible.
