Carla's apartment was absolutely perfect (looks just like it does in the pictures), and Carla is a kind and helpful host. The studio was so comfortable, quiet, and adorable (and I loved looking over the city/river landscape from the skylight in the loft. So fun!). It was extremely clean (cleaner than most hotels!) and very well-equipped (there's everything you need in the kitchen, including tea, coffee, and basic spices if you wanted to make your own meals), and I immediately felt at home. Carla is very considerate and provided a useful guidebook to Porto, plenty of clean towels (a large towel, a face towel, and another hand towel), clean sheets, and the bed was super comfortable. The apartment was also extremely quiet and dark at night (if you drew the shades), and has a remote-controlled heater/air conditioner, which made for an amazing sleep at the end of a long day. There was a hair dryer, fresh toiletries (bring your own toothpaste, of course), umbrellas, and even an emergency local cell phone if you needed it. It is very safe (I was a solo traveler) and in the best location. The apartment is right beside the most happening places in Porto, conveniently located within walking distance (5-10 minutes) to the metro, the riverfront, the tourist attractions, but it also feels like you're living amongst locals. There is a small and cheap grocery store next door, and just down the street Carla recommended a charming local restaurant where I had the nicest (and very cheap) meal in Porto. Carla is very responsive, informative, and reassuring in our communications with each other. She is also very punctual, professional, and reliable -- she waited for me at the studio when I arrived and was there when I checked out. She even let me keep my bag at the apartment for a few more hours (and was there when I was ready to leave for the airport)! Everyone I met in Porto was super friendly, and I couldn't have asked for a more perfect Airbnb experience. Carla was an absolute pleasure to interact with, and I will definitely be back!
