We enjoyed our 7-night stay here. We decided on this apartment because we needed two beds and a convenient prime location. It was a very short walk to the river, supermarket, train, and restaurants. The apartment was very clean with aesthetically pleasing décor and lots of natural sunlight. The kitchen had everything we needed for breakfast (it even had Tupperware that we used to take food with us for a picnic (win!)). However both of the beds and pillows were very hard (we are side sleepers so our shoulders and neck hurt a lot). Claudia greeted us by the entrance, gave a tour of the apartment, and went over the map of Porto (which was incredibly helpful)! It was very easy to get in touch with Claudia via Whatsup. As others mentioned, the apartment is located across a hotel so there were large buses and people frequently outside (this was never a problem for us). The light in the hallway wasn’t working when we arrived. Claudia said she had called someone but it never ended up getting fixed. This was really frustrating because the hallway was really dark and we always needed to turn on our cellphone flashlight to see the keyhole (we ended up using the actual key instead of key card as the key card wasn’t working either). Also, there are only 5 channels on the TV so bring an HDMI cord and entertainment device if you plan to relax by the TV in the evenings.
