Marta’s apartment was one of the nicest places we stayed at. The apartment was clean and location was perfect. Walking distance to everything. We had 2 toddlers and 2 infants and 5 adults and even with that many people, the apartment had ample amount of space and quiet at night for kids to sleep. The apartment doesn’t have AC so it did get hot at night sometimes even with fans on. The best part was that there was a cafe/restaurant downstairs which made getting coffee and food much much easier. Marta was very attentive and responsive to our questions. She even went above and beyond and didn’t charge us anything extra when one of us broke a plate. I would definitely recommend staying here while you’re in Porto.
