Awesome communication from Gary beforehand, we saw a sign for one of the 2 car parks he recommended and headed there and not the flat. I've driven loads abroad but a combination of GPS wobbles, unexpected no-entries and one ways, as well as following the signs which took us into narrower and bendier old roads before disappearing, meant we arrived late, really frazzled and with a scraped hire car; we apologised profusely I think this may have inconvenienced his waiting mother. Not sure what the morals of this story are apart from sticking to Plan A, don't rely on signs to take you all the way and avoid Garmin GPS products.
Thankfully, it was all worth it in the end. Gary's flat was well-equipped and perfect for our 2+2 family. The AC was more than a match for the August heat, the latter and rooftop washing line meant our laundry was dry within a couple of hours. The 2nd bedroom was fine for our 2 girls but the roll-out bed does take up all the floor space so it is pretty much a room for sleeping. Thankfully, the lounge area was more than adequate for chilling.
We LOVED the location. Great local buzz, particularly in the adjacent Cuesta del Rosario which also had the awesome Heladeria Bolas: I can still taste their Sevillian Moorish ice cream (in a good way). Our favourite local restaurant was La Bodega de la Alfalfa but we had a great tapas crawl around the La Plaza Alameda de Hércules: Duo Tapas, just off it, being the highlight there.
In short, highly recommended.
