3 of us stayed at Maria's home for three nights. Our stay was pleasant. Maria went out of her way, she offered us train station pick-up & drop-off. That really made things much easier. So nice of her!
When we got to the apartment, Maria showed us everything in the house. Even though we don't speak Spanish, she kept google translation handy. The communication was just fine.
The apartment is conveniently located. Maria showed us the map, the bus route and how to use the bus system. We took bus daily (less than 10 mins bus ride to downtown Sevilla) and got familar to our way pretty quickly. There was a big supermarket right at the corner, just a couple mins walk from the apartment. The neighbood might be a depressed area, but the local people are very friendly.
Sevilla is incredible beautiful. We had a blast!
