I had a wonderful 3 days stay in Almansa !
On the pratical aspect : The access to the appartment is easy and can be autonomous, the host communication is also very reactive. The flat is charming as in the pictures and contains everything that you may need for a short/mid stay (the kitchen area is bigger than I thought).
The location is near perfection, giving you either the opportunity to explore the small streets of Sevilla center or go along the river to quickly and easily access most importants touristic places.
On a subjective aspect : I personnally believe that staying at Almansa was a true authentic experience! The bohemian/romantic style of the place fit perfectly with the energy of the city. Waking up in a flat bathed by light and having your breakfast on the Patio while enjoying the view on some old cathedrals is a truly great way to start the day !
* As you probably readed under, the flat is not very well sound isolated. Not much of an inconveniance in my opinion but consider having earplug if you are a light sleeper :)
