The location of the house is good, and it's ~15 - 20' on foot from major landmarks in Seville and is also very nice place for a short stay. However the communication as a whole with the host has been problematic.
The last day before coming to Seville, we tried to verify this "Free parking on premises" feature with Pepe and at this point he informed as that this information was incorrect and that wasn't available. He attributed that to a translation error. After this discussion he changed this setting to "Free on-street parking". This is also inaccurate since he doesn't have a dedicated on-street spot to offer, so, at the end of the day, we were on our own to find a parking spot.
I suggested that, since this was an error on their side (translation error or not) and since I would have the car only for one of the days of my stay, that they should compensate us for our cost for parking the car in one of the cities parking locations. Pepe was reluctant to do this, offering us instead free late check-in or extended checkout hours. These suggestions didn't solve our problem though. The next day (21/10/2021 - day 2 of our visit), I repeated my request to compensate us, at which point they offered to let us use his own parking spot (a parking spot they hadn't mentioned in our initial discussion and one that I was unaware of). At this point though this solution was irrelevant, since we had already returned the car to the car rental company.
All in all, the house is alright, but I found the host reluctant to help and to solve a problem they had created in the first place.
