The location of this airbnb is absolutely perfect; it's right in Alameda de Hercules, and you could honestly stay here without ever leaving the area because everything you need is so close. Still, it's an easy bike or scooter ride to the main part of town! The private terrace is lovely for sunbathing, as well. We locked ourselves out on accident once and someone from the property company came to let us in within 20 minutes, for which we were incredibly grateful.
Unfortunately, that's where the positives of the property end. Upon check-in, there was a horde of flies in the studio. The person from the property company seemed uncomfortable about the flies, said he didn't know why there would be so many, and gave us ant repellant(?) as an attempt to remedy the situation (obviously, that wouldn't work for flies, so we bought our own fly-repellant products). The floors also turned the bottoms of our feet completely black within 10 minutes of first walking on them; it was truly disgusting. I mopped the floor twice myself and ended up ordering a swiffer in an attempt to clean them (it still took multiple rounds of the wet swiffer pads).
Most unsettling, however, was the fact that there was blood (most likely from a pimple) on the comforter. I sent a picture to the property management account, who said the property owner insisted that she'd cleaned them herself earlier that day, and instructed us to put the dirty sheets in the laundry room for the owner to take care of. We did so, but after they sat in the room for a few days, we decided to wash them ourselves (not that we mind doing laundry– just don't tell us you would take care of it if you aren't going to). There also appeared to be mold on the shower curtain and walls.
The wifi is abysmal. Seriously terrible. I genuinely think it's misleading that the airbnb is listed as having wifi, because truly you do not. There is a wifi extender in the studio (I assume the router is in the main apartment below), but it is bascically useless.
My partner and I aren't particularly picky, we were shocked by how dirty the place was when we arrived. It would maybe be okay to stay for a night or two if you'll spend most of the days out and about, but even then I would recommend a hostel, as it'll be at least similar conditions, if not better, for a lower price.
