Amazing! Arguably the best Airbnb experience I've had. Alexis greeted us on the street where the taxi dropped us off (since they can't make it down the small street the apartment is on) and after check in invited us some tintos de verano at a nearby bar as she suggested activities and gave us tips on how to explore the city. She is lovely and super attentive - even ordered us a taxi on our last day.
The apartment is quaint and lovely, comfortable and it has air conditioning (a life saver in June!). It's fairly close to downtown (a pleasant 15-20 minute walk to the Catedral) and it's surrounded by authentic stores, bakeries, restaurants etc. It's a great place to stay if you are someone who'd enjoy observing day to day life in Sevilla, but wants to be close to the touristy stuff as well.
