I spent two days at Casa Formosa in August and I have to say it was a very pleasant experience. The apartment in general is very clean, my room was tastefully decorated and impeccably clean as well. It is very centrally situated with metro and buses very close. There is a very warm ambiance and the people staying there at the same time seemed to enjoy it immensely as well. Joao is an exceptional host who really goes out of his way to help, advise and make sure that our stay is as perfect as possible. He is an absolute star and I would recommend Casa Formosa without any hesitation whatsoever and if and when I go back to Porto I would certainly consider returning there. Thank you Joao and keep up the good work!
