My partner and I stayed here for a full week as part of a three week honeymoon in Portugal. We had hotels in some of the other places we were staying and were intentionally looking for a place where we could feel like we lived in the city -- and this hit the mark on that 100%.
The communication and check in processes were smooth and easy, and once we got in we were struck by how lovely the apartment was -- lots of light, very clean, and enough kitchen utensils to cook some breakfasts ourselves. Also, the washing machine was a HUGE help midway through our trip!
As far as locations go, this is really tough to beat. It's a quick walk from the subway station if you're coming in from the airport or train station. There are grocery stores nearby if you want to cook in the apartment, and tons and tons of places within easy walking distance. The neighborhood also has a vibrant nightlife which is very fun to experience sitting in the living / dining room with the windows open -- but if you close the windows and shutters it's very quiet indoors, too.
All in all, this was such a beautiful way to experience Porto. We had an absolute blast and would highly recommend this location to anyone looking to fully experience the city -- especially anyone who loves walking around new places to explore every nook and cranny!
