Catarina & Alexandra are great hosts that i can really recommend to everybody travelling to porto. their apartment is very central, it is big with 3 guest rooms. you have a nice little balcony, a clean kitchen equipped with everything you need, a good bathroom and an extra restroom. also there is a cozy tv room. they have been very flexible and kind upon arrival. they have provided us with all kinds of support and information about the city. so all really perfect!
