Maria Jose and the apartment were both great. It started with Maria jose waiting for us on the street close to 23:00 when we arrived. She was very welcoming and a treat of bread and butter and some tea waiting for us was more than welcome. She left us with a bus card loaded with 14 Euros, which basically served us for our entire three days trip.
The apartment is a bit off the central town but transportation was easy and it was actually a great experience to leave in a real local neighborhood. The neighborhood itself is really interesting, filled with beautiful murals. Not a place to visit as a tourist attraction, but it was part of the whole Sevilla experience.
