My husband and I stayed at La Féria for one week during our October trip to Sevilla.
Pros:
A very local, non-touristy area with great restaurants, bars and cafes at your doorstep
Nice, clean, modern building with all of the basic amenities you would need
Comfy big bed. The noise from the street didn’t bother us and we slept great
The only negative:
The WiFi is really not suitable for working from the apartment or taking Zoom calls which we had planned to do for the week. This was problematic
