This is definitely the best place I stayed in Spain after a month of traveling around. I was alone and it was spacious for me so it would probably also be great for a couple.
The bed was fairly comfortable and the AC kept the whole space cool. There is only one window into the central area of the apartment, but it lets in nice natural light when the curtains are open.
The kitchen has everything you might need including oil, salt, pepper, tea and coffee. I cooked several times without any issues. It was also great to have a little dish washer and laundry machine. Laundry dries very quickly outside in the heat/dry weather. As mentioned by others, the pool is tiny but still nice to cool off after the heat in Sevilla.
Last, but not least, the staff was amazing. There was someone available all day through WhatsApp if I ever needed anything (I wasn’t sure how the plug to the sink work so she happily helped).
