I warmly recommend Rosa Maria's apartment, where we had a very pleasant stay. The location is perfect: 3 min walk to the Cathedral and the Alcazar but in a quiet inner courtyard where one can have a good afternoon or night rest insulated from the noise of the street. All the other major attractions are within walking distance. The place is spacious, newly furnished, sparklingly clean, tastefully decorated and equipped with everything useful. Rosa is a considerate and helpful hostess, who very kindly left for us traditional pancakes, mandarines and a bottle of wine. Her English is very good. If you take the bus from the airport, the best stop to get off is probably Paseo de Colon. It takes about 10 min to get to the apartment. I was initially suspicious because there were very few reviews but this is due to the fact that the apartment only became available for renting from February 2019. I was very pleased with my choice. Many thanks, Rosa!
