Dino and Ines are such great and wonderful hosts! We were greeted by Dino at the apartment. Even though we were running hours behind schedule, he was able to meet us at the apartment to greet us and walk us in. On the plus side, they even baked us a delicious cake and got us some Portuguese wine and cheese! The hosts were very good with communication and gave us a lot of good tips for Porto and the surrounding neighborhoods.
Now, for the apartment and location. It was very stylish and well decorated. The studio was spacious enough for my wife and I to feel comfortable and relaxed. It came with a lot of amenities that we were looking for. The apartment has all of the modern touches that you'd expect and see in the pictures, so don't be fooled by the exterior of the building! The location of the studio is on a non-busy street and is quite quiet, which was something we were looking for. It was basically empty at night, and we were there on a weekend. Expect to walk about 15 minutes to the center of Porto and 30 - 35 minutes to the waterfront. There's not a lot of food or bar options nearby, but that was OK with us. There's a few grocery stores nearby, but we didn't make use of it.
Overall, we had a great time in Porto and staying at the apartment. The hosts seem to really enjoy the experience of meeting travelers from all over the world and not so much focus on making money. They will be helpful with whatever you need. For the value and location, this place is top notch!
