We had a great stay in Fatima's apartment, and I would definitely recommend it as a place to stay in Seville.
The apartment is lovely - two good-sized bedrooms, plus a spacious lounge/kitchen and bathroom. All is very clean.
The location is great - in the centre of the city, and within easy walking distance of all the sights. Plus with shops and restaurants nearby.
Fatima was a great host too - very quick to respond to any questions before and during our stay, and she was flexible and accommodating of our check-in/check-out times.
In summary - a great place to stay!
