i do recommend this studio. everything was perfect. studio was well-located ( really perfect), cozy, clean and nice condition. especially view was amazing. actually it was 2nd time to visit Porto so i knew where is good spot to stay, so that's a reason why i booked this studio, but Mario's studio was nicer than i thought. and also Mario is friendly, gentle, nice person. if u need some help, he would help u whenever u want. anyway, thank u so much and hope to see u soon :)
