The apartment is great! really well located in the city centre of Seville. The place has everything you need to be comfortable: kettle, microwave, toaster, washing machine, stove and so on (a part from a moka! so bring your own if you want a coffee different from Nescafe!).
The apt is at the third floor with no lift (so you know). I wish I understood this when booking as I have problems with my knee.
The terrace is outside the apartment, available through the stairs (as stated in description).
Overall, good for a couple with a small child. It has a shop in front (mon to sat, 9 to 22:30), where you can also buy coffee (there is a self service machine). Communication with Antonio is easy and great. He replies quite soon and with lots of clarity. Check in is automatised (self check in and self check out) which makes the experience less stressful.
Strongly recommended
