I have stayed at Natalias house for 6 weeks during June and July. The apartment is really good. Enough space, super fast wifi, fully equiped kitchen, laundry machine, all detergents available so you dont have to buy extra products to feel comfortable.
Natalia is a wonderful and warm person. She will greet you personally and share all the good places and things to do to truly experience sevilla.
The apartment is a little outside the city center, but you have easy access to public transportation that will take you there. The busstop is just around the corner from the apartment. Bikes are available just 3 min walk and Cabify is between a 5 eu ride into feria or 10 eu into Triana.
There are supermarkets, pharmacy, health/nutrition shops around the corner. In terms if eating out there are not that many options, but you can order in via glovo or take a 20min busride into town.
An amazing apartment and really good value for money.
