We were a couple visiting Sevilla for 2 nights. Alfredo was super friendly and helpfull.
The place is very basic and simple. So if you are out all day its ok.
But the internet connection was very unstable. If you are working during your stay, the internet would be a concern.
But if you are out all day, you can live with it.
And you also have neighbours next to you, so you can hear them.
Overall an ok experience, and Alfredo was great.
