The Blue Balcony House is in a great location for seeing all of Porto given its proximity to the Bolhao Metro station. We took the Metro everywhere, from the airport to the coast to the across the Douro for Port wine tastings. You can drop your luggage off at their welcome center at the Casa de Musica Metro stations, and walk around a bit and have coffee until the apt is ready. This was a very convenient feature. From Casa de Musica station, you're just a couple stops away from Bolhao station and a few blocks away from the apt. A recommendation for the area: after the sun goes down on weekends, one the commercial streets down the road turns into a pedestrian mall closed to cars and is great for strolling, people-watching and trying pasteis do nata. There's also a Pingo Doce market about 5 blocks away in the same direction so you can stock up your fridge and pick up some (absurdly) cheap Douro wine. Overall, a good place to stay while exploring Porto. One drawback I feel obligated to mention is the significant noise from the road just outside, even at night. With the windows closed and the shutters locked, the noise is muted, but still evident. For those who like windows open or are bothered by the sounds of a city, I would take this into consideration. We only stayed here, so it may be that road noise is a feature of all apartments in Porto. But that said, for the location, service, and price, the Blue Balcony House was a good place to stay for our three days in Porto. Thank you TPC.
