I gave 4 stars in large part due to the excellent location of this apartment and Valentino's promise to make some key improvements. (I was his first guest. I am a Super Host who needed renter feedback when I got started, so I appreciate his willingness to make his place better and better.)
Location -- this is right near a water taxi and right in the middle of the action. Very central. It was clean. Check in was super smooth, getting greeted by his friend Valentina who gave me the keys and showed me around.
Here are questions to ask before you rent:
1) Is Internet now installed?
2) Is the stove working?
3) Do I get more than 1 towel?
If the answer is yes, that is great news.
Note: Due to it's proximity to the water, there are some nights where "high tide" impacts this building. I walked out one night and my foot was submerged in water. One block away, and in most of the city, this was not true. The next couple nights things were fine. So, just know this is a possibility -- unique to this building, but a function of location near water.
Overall, a good place to bunk for a couple days if you want to be in the center of the action with no frills.
