Carlos "duplex" (by which he means two level apartment) is a true gem of an Airbnb--the best one I have ever stayed in, anywhere! Stylish, elegant, comfortable, beautifully furnished, yet cozy. All the modern conveniences, and more -- plus a perfect location from which to explore Sevilla (on foot; no taxis needed). The narrow street outside is used mainly by pedestrians, and at each end of it is a small, typical Spanish plaza, with busy little coffee bars and indoor/outdoor cafes and restaurants serving excellent food at reasonable prices. A bakery with wonderful breakfast sweets and breads is just a minute down the block, and a full-scale supermarket is less than 5 minutes farther (plus other smaller vegetable and fish/meat markets). Carlos is readily available by text, if you need anything, and he meets his guests when they arrive and provides a list of recommended restaurants in the area; I went to several, and was delighted with them! The neighborhood is lively until almost 11 at night, since the Spanish usually have their evening meal late; but I carry earplugs wherever I go, and I had no trouble sleeping--and could even sleep late in the morning, since nothing really opens up till about 9. I loved this place and it would be my first choice of places to stay if I ever return to Sevilla some day, which I hope to do!
