This apartment is a great location right next to the Rialto station. However, that means it is not quiet (street traffic noise). Also, note that the A/C is not in the bedrooms upstairs, but rather in the hallway between them, so it's fairly warm in the summer even if the A/C is constantly on. Also, it is a vertical layout with narrow stairs without a banister. This can be dangerous for smaller kids or older adults, and should be taken into account (our kids were 8,10,12 and it was a source of worry). The one bathroom is at the middle level, with stairs up to it without a banister. The vertical layout also means WiFi is good in the first floor (kitchen and living room) but nowhere else.
Finally, if you need to store luggage, you should probably ask well in advance as by the time they told us we could, it was too late (already had to store our somewhere else as we had left the previous place). The entrance hallway is behind a locked door, so I'm guessing you would just store it there after the previous guests leave at 10am.
