Rosa Maria was great! We originally booked for 3 nights, but had to change to 4, and she was able to accommodate us. We arrived very late, but she was there to let us in. The apartment is clean and very comfortable. The location is in a quiet neighborhood with great architecture. There is a bus stop nearby, or you can make the 15 minute walk to the touristy part of Sevilla. There is a grocery and plenty of restaurants near the apartment. We had lots of transportation questions, etc. and Rosa Maria was incredibly thorough and prompt in answering anything we wanted to know. This was our first experience with Air BNB, and it made us certain we'll do it again!
