Manuela's apartment is much roomier than the photos suggest and provided for a comfortable 3 night stay for our family of 3. We enjoyed the huge windows overlooking the street, and despite it being a popular street on a main drag, the unit was very quiet at night. The shutters function as blackout curtains and we slept very very soundly on comfortable mattresses.
The shower was heavenly...roomy and powerful with plenty of hot water! The rest of the amenities are pretty basic but functional with a nespresso machine, small stovetop and refrigerator. The building has been renovated with high ceilings and the stairways and hallways are spacious, modern and clean. Albeit a bit expensive, I did use the laundry room.....you pay 9 euro at the store downstairs and they give you a key to the room along with detergent. Both the wash and the dry took a really long time, in total about 5 hours, so I don't recommend using the washing machine to anyone who is planning a one night stay!
Check-in and checkout went very easily and we were able to store our luggage in Manuela's shop downstairs. The location is incomparable! It is perfect for sightseeing, just behind the Se, near the Sau Bento train Station, a 10 minute walk from the bus depot (very convenient if you are planning to take the bus into town from another city) and right around the corner from the 500 bus that takes you to the beaches. There are lots of wonderful restaurants and shopping within a 2 block radius so you won't have to go far, and it is also just a few blocks away from the waterfront to take a Douro rivier cruise or dine alfresco by the water.
We really loved staying here and would not hesitate to book again for our next trip to Porto!
