This is a great apartment with easy access to all the main sites (casa pilatos couple of mins away which is a must visit). Javier was incredibly responsive and welcoming, was waiting for us at 8.45 pm on a Friday without any complaints. Gave us all the local tips and left us some treats including a delicious bottle of red.
The apartment is clean, not as noisy as I expected being on the ground floor (you can hear some noice if you are sleeping in but it wasn't too bad for us). The showers are great, only issue is the ensuite bathroom smelt a bit because of the sewage issue in Seville (nothing to do with the flat which was spotlessly cleaned). The flat is decorated beautifully. Javier also let us leave our bags there as he didn't have a booking on the day we left. Highly recommended
