We are a family of five and stayed for a little over a month. The apartment is exactly as you see in the pics, maybe a little less well mantained (big dents on the floor and walls), but considering is a rental was very good.
Location was just perfect. Walking distance to Palermo and to all buses and subway.
Gym upstairs was well equipped and clean with a great view.
Security in the building was available 24hs what made it great for coming back late at night with kids
Wifi wasn't great. We were working during our stay and unable to send and receive word docs. what made our job very difficult. We had no internet for 3-4 days what caused us big problems. The lack of a land line made us be without any type of communication.
Carolina was very responsive and quick with this issue and other things we needed during our stay (i.e. not enough chairs for five). She was always available within minutes and found solutions for all the issues (other than the internet that was more related to the company than anything else)
I highly recommend this place and would come back (probably when I know I will not need internet so much)
