The apartment was clean and comfortable for our family of 5. The bed, pillows and blankets were so comfortable!! Being on the 4th floor (considered 5th in US) walk-up is tough on the legs, but most of Porto is climbing up stairs and hills anyhow. and we felt lucky to be higher up-- we got great sunlight in the two front bedrooms that faced the river every morning.
Porto is a very safe city, so even though the streets around the apartment seemed to have fewer pedestrians and boarded up buildings, we always felt safe. (If we were in Chicago, we'd never walk down such street at night. It's very different in Porto.) It seemed that Porto was going through a revitalization in restoring such beautiful historic buildings. San Miguel is a nice quiet street-- On the east end, there is a spot with amazing views of the city where many people seem to go for photos, and is situated next to a convenient set of city stairs that leads to the "Flowers Street." On the other end, there is a cute convenient breakfast spot called Cappella 51, family-run, with great food and service. Luisa helped us find offsite parking , a 7 min walk away-- 20Euros for 72 hours with free access during the stay. The apartment was quite central to various sites.
Luisa readily answered any questions, offered many suggestions, and was a wonderful host. She made checking in so easy. Porto was the highlight of our trip to Portugal!
