We really enjoyed our stay at this great place in such an awesome location (only 3 mins away from the Cathedral). The person we had to contact was nice and quite responsive. The apartment was spacious and brand new, including the furniture too. The AC is not that warm but that should be fine since Sevilla is not as cold as other cities in Spain.
Do note that the place is located next to some bars so it can get quite noisy at night when you sleep. Also that there are constructions happening currently, so it's also noisy during the day but again it should be fine if you plan to go out and explore the city!
Thank you :)
