This is a good place to stay in many ways. West Sevilla has an extremely good connections to the center.
But you will also find nice cafes, restaurants, etc. in the neighborhood. Keep in mind the Spanish daily rhythm, with a siesta in the afternoon and a diner at 9 p.m.. Witch is less noticeable in the center. But in return in the West you offen have better food for a lower price and before all: more Sevillian people around you.
The neighborhood where you stay resembles an Andalusian white village. white houses, flowers.... and is very quiet.
The room and bathroom are very good, the hosts are friendly and helpfull. Another advantage of this place is that you can get some space in the fridge and also heat up food, so you don't always have to eat at a restaurant. The cozy patio offers coolness and tranquility in the evening. The airco in your room is a gift from heaven on hot days.
About Sevilla: it is a beautiful city so many tourists are coming. Of course there is the monumental center, but it is also nice to discover the atmosphere in the different neighborhoods.
On the other hand, some (even central) parts seemed to me a little like a ghost town after 2 p. m.: many tipical shops (ferreria, merceria, shops with self-made ceramics etc. ) close and stay closed for the rest of the day, many are even closed for weeks during summer.
The covered markets are very pleasant, but even there many shops stay closed. However: you can eat tasty and cheaply there during the whole afternoon, f. i. in the Triana market.
The best time to visit Seville seems to be during spring, Antonia told me. I enjoyed being there in summer, but for the next time I'll follow this advice.
