Catarina was a wonderful host! Responded very quickly and was very accommodating to all my requests. Check-in instructions were super detailed and helpful. The place was welcoming and spotless, the bed was super comfy and the shower was great. The kitchen had all the items you'd need (including coffee and tea as a courtesy) and was very clean and well presented. Catarina's place is definitely a little treasure if you want to stay close to Massarelos. I would definitely recommend this place to anyone who wants to spend a few days in Porto.
