I stayed 3 nights in Sonia’s apartment. She is super nice and very discrete. She has some rules which is completely understandable as she lives in the appartement and this is not an hotel.
The apartment is nice and very clean.
Location is convenient, easy to use the bus to get to the center or you can walk (I would stay 30min to the main attractions).
Definitely enjoyed my stay in Sevilla and will for sure come back !
