This might have been a 3-4 star experience for me, but the host pushed me over the edge regarding the WiFi. Before arriving, I’d read a review that the internet here was really good, but I still messaged the host and advised that I’d be working and heavily reliant on great WiFi. I asked specifically whether I should invest in a portable WiFi dongle or alternative WiFi in case, and he assured me it was great and not to worry.
It didn’t even work.
Through a busy Monday with work, in which I had to tether off my phone’s shoddy 4G internet (that’s another issue, the apartment is in a bad 4G place with low bars), the host sent two different guys to resolve the internet issues late in the afternoon. One of them advised me that this old building couldn’t get Fibre so was reliant on copper, and that the internet in this apartment had always been bad. I purchased my own Vodafone SIMM with 70Gb so I could get through the week, but what really annoyed me was the host giving up on the WiFi with, “It’s not my fault.”

Unfortunately this forced me to note a few things that I normally wouldn’t have bothered to note.

There’s a pointless broom brush without a handle, no dishwashing liquid or tea towels for an apartment most people would visit for a week, dirty skirting boards and windows/window frames (though the sheets, towels, house itself appeared very clean). The toilet tilts with you when you lean over to wipe, so be very careful you don’t topple and the flush itself doesn’t work very well. There’s a broken wooden toilet paper holder, broken towel rack and a general feeling that someone gave up on maintenance to this place long ago.
If you’re desperate and do not need to communicate with anyone over WiFi or 4G, and you want to be really close to the town centre, this might be an acceptable place to stay.
It’s a shame, with a little bit of maintenance, some consideration that people don’t travel with dishwashing liquid and teatowels, a WiFi overhaul, and a much better Covid-friendly clean, this could have been a much better experience.
On the day of my checkout, there seemed to be a miscommunication. While I was advised by my booking person that my checkout was later that afternoon, I discovered by a screeching cleaner that it was in fact mid-day. And when I say screeching, I mean, all the neighbours came out to see had been brutally murdered. I’m not even exaggerating. She screamed for ten minutes while I furiously packed.
I sent an apology to the host for overstaying and an explanation, but left in distress and sat at the airport for 8 hours.

This was my only negative experience in Seville. It’s a great city that I’ve visited many times and will continue to do so, I just won’ be staying at this Airbnb ever again and wonder how it got ‘Superhost’ status.
