We loved our stay at this apartment! It was spotless and centrally located in the historic district, just as we wanted. We never met Filomena or Ana, but they communicated often with helpful information in advance of our visit, and Walter met us at the door (and with a bottle of wine in the fridge) and completely briefed us on the apartment, what to do and where to eat in Porto. We appreciated his patience, as travel delays put our arrival well behind schedule.
The view from the top-floor apartment is just as advertised, breathtaking, and worth the steep climb with luggage up the building's staircase. We spent every late night after dinner sitting on the small balcony and gazing at the lights of the waterfront and the port warehouses in Gaia across the Douro river. We appreciated the small combination washer/dryer and used it a couple of times. Be warned that the bedroom is in an upstairs loft that you get to up staggered wooden steps. Be careful there. The bed was very comfortable and the oscillating fan was essential during the heat wave that hit while we were there. The apartment is not air-conditioned.
It was a great place for us to say during our visit to Porto and we highly recommend these hosts.
