Me and my friends had a really nice stay in Fabio's appartement. The location of the airbnb is perfect and we explored the whole city by foot.
You can reach the hosts per whatsapp or airbnb and they answer very fast and friendly. For your stay in Sevilla they give recommendations for sightseeing and restaurants which whrere really helpful for us.
The appartement has everything you need for a city trip. Also the kitchen is well equiped so if you want you can cook by yourself and enjoy your food on the rooftop with a lovely view :)
