The days we spent at Renato's place were amazing. The house is very nice, super central (we never took any public transport but reached everything walking) and it has everything you could need during your stay there (including a very nice and silence little garden!).
Renato was one of the best host ever! He waites for us for the check-in and gave us a map of the city and all sort of useful detailed information and tipps to enjoy and discover Porto. He was very kind, always available for any doubt, question or information and he always paied attention that everything was allright. We had a wonderful stay at Renato's place and we would definitely come back! Highly reccomended!
