The flat is slap bang in the middle of the historic part of Seville. Moments from the Alcazar and Cathedral and well placed for getting to know Seville, a truly amazing city (we had a great time).
With that, though, came a lot of noise at night unfortunately, made worse by the reverberating narrowness of the street below. Revellers, street cleaners at 4.15am for example had us waking several times during the 4 nights we stayed. The flat could benefit from a second set of doors, like the flats opposite, to keep the noise out.
It was clean, and stylishly decorated (an ex art gallery), with an elevator that arrived straight into the kitchen!
Ignacio, although we didn't meet him, was very communicative, and his love of Seville was easy to see, with his wonderful list of recommendations.
In retrospect, we might have chosen a less central area to stay and not on a busy pedestrian street. However, for those travellers who can sleep through anything, this would be a good choice.
