The apartment is really nice and just like in the photos. Wifi worked great and I worked from there for the week I was there. The location is great and close to lots of nice restaurants, as well as Vucciria market. The sofa bed is comfortable for one person to sleep on as well. The ONLY thing to mention is that the street below has a lot of bars that blast loud music in the street until late at night. The apartment has good windows but the sound still gets through especially on the weekends. I recommend bringing ear plugs for sleeping. Overall this didn't bother us too much as we enjoyed the lively atmosphere of the area.
Note that if you want to check in after 8pm you will be charged a 20 euro fee.
