We enjoyed out stay at this apartment, it was clean, central and had all the amenities one could need!
We were unfortunate that our arrival time due to pre-booked trains was beyond the suitable time for the host. This did negatively impact on our stay and I did feel I was causing "hassle" on arrival. I did not have any opportunity to ask questions about things to do in Seville which I see other guests had done.
I would advise that arrival times be clearly communicated to the host on booking this apartment and directly finding out if this is or is not suitable for the host.
