We were welcomed by Karmen before the check-in hour because we were early, but she was kind enough to take our luggage and give us some advice on what to do to kill our time.
The appartment itself is super clean, really cosy and what I personally liked the most was the silent. Despite sitting next to a very busy square, once closed, the windows do not let any noise in, resulting in a good night's sleep!
Karmen is a very warm host and will help you where she can.
In short, would recommend and if we ever come back to Seville, we are going to book another stay here!
