We had a great time. The flat is well-placed for enjoying Seville, and it had everything we needed. It is modern with a useful kitchen area and a great shower. Our only issue was the heating. We found the apartment a bit chilly in January even when using the heater, although we did note that many public places (bars, restaurants) were not heated as much as might expect for similar temperatures in England. The surrounding area felt safe and it was not too far to walk in to the centre of Seville - about 20 to 30 minutes. There are plenty of places to eat and drink 5 or 10 minutes walk away, in the Feria area or on Alameda de Hercules, if you do not want to go in to the centre. The flat is also close to the Macarena Basilica, and the remaining section of the old city wall. We found plenty of nice vegetarian food in Seville - the Happy Cow website was useful for this.
