We greatly enjoyed our stay at Rebeca's place. The unit is very modern and clean, with floor to ceiling windows, two twin beds (which we pushed together to make a king bed), a Nespresso machine, microwave and refridgerator, and a full bath (shower and toilet in separate areas).
The location was superb. The unit was one block away from Las Setas de Sevilla, a major landmark (a modern market covered by a plaza with mushroom shaped parasols above, hence, "las setas" or "the mushrooms"). There were shops and restaurants just downstairs from the unit. We were able to walk to all major sights in about 15-20 minutes.
The unit is conveniently reached by taxi and buses. From Santa Justa station you can take bus number 32 three stops to the Ponce De Leon stop and walk further westward two blocks to the unit. A tarjeta multiviaje (multi-trip transport card) can be purchased at the tobacco stand at the train station. One tarjeta multiviaje can be used for multiple passengers. It also works for the Sevilla tram that runs along Avenida Constitucion.
Rebeca furnished us with several restaurant recommendations. One of our favorites was Los Coloniales, an excellent tapas bar in Plaza Cristo de Burgos, a plaza that is just next to the unit's building (it is a 2 minute walk). A bit farther walk, but also in the neighborhood, is El Rinconcillo, one of the oldest tapas bars in the city, famous for the way the waiters tabulate the bill (writing in chalk on the bar). A sort walk west on Calle Imagen (about 3-4 minutes, past Las Setas) leads to the shopping area of the city with Zara, El Corte Ingles, and an unimaginable number of shoe shops. If you head south (a left turn at or one or two blocks past Las Setas) you will pass through the shopping area to the major tourist areas.
