Mario's place is sweet but small. I had a lot of issues unfortunately! First of all the entire apartment building is a hotel kinda thing that Mario runs. Every apartment has been posted on different websites. When you arrive Mario or his friends always are there to greet you and show you your place and things around Porto. THE location is great as it's central to everything but it gets extremely loud in the night as there is a pop bar right outside. The apartment is on a side street and so the rooms get really hot. I asked for a fan but was immediately denied. I actually fell sick and got heat rashes during my stay. It was unbearable...and a little bit of a put off. I requested twice for a fan but was told it's fresh in the nights but no part of the nights were fresh. I used to keep the windows open but the music from the bar would be so loud that I couldn't sleep. The bathroom shower would fill up fast and couldn't drain the water fast enough. The room was definitely neat and clean and had all amenities but I wouldn't live here again especially not with the attitude Mario had.
