I can’t say enough good things about Natalia and Oscar (and the 3 cats). Natalia and Oscar truly are amazing hosts, they are the very best there is. They are very gracious, and easygoing, and right from the start told me to make myself at home. They are very considerate and thoughtful, and one of the first things they asked was what I would want them to leave as a small breakfast each day (Natalia said that she and Oscar know that people staying with them are busy, so they want to make sure guests at least have something small to eat in the morning- I thought that was so sweet of them! They really care a lot about the guests.) Whenever I had questions about anything related to the apartment (like a reminder of where something in the kitchen was) or Barcelona (such as good bookstores/comic book stores), it was clear from their responses that they were so happy I asked. I loved all the conversations we had over coffee and learning about them (both Natalia and Oscar are really artistic, and it was so cool to learn about their interests, what they currently do, and what they have previously done). If you get the chance to stay with Natalia and Oscar (and the 3 wonderful cats) do it!! I not only had a wonderful time while I did research in Barcelona for my studies, but I also made two new friends. I have to say that meeting Natalia and Oscar and getting to know them was one of the highlights of my whole trip.
