Highly recommend. Hedyeh’s place is very centrally located in the old town of Sevilla, right next to the main square (Metropol Parasol) where you can use it as a central point of navigation within the old town. From here you can also take a taxi. On our day of departure we walked for about 1 minutes from her house to the taxi stand and went to Santa Justa train station with €5, no waiting time.
Her house is lovely and super clean, with comfy beds. There is a spacious rooftop terrace where we can hang our laundry. On weekend nights there will be some noise from the street, however understandably this is a common issue in the old town area and we were not too bothered. We did not use any form of transport when touring around the old town, as it is always walking distance from here to all major sites - Flamenco Museum/Plaza del toros/Cathedral/Alcazar etc. Location is unbeatably central and easily recognizable.

Hedyeh is very helpful and responsive. We had an unfortunate event in Sevilla and lost our keys. Upon calling her, she guided us on what to do, where the nearest police station was, and waited for us to come home (since we no longer had the keys).
Overall a very pleasant experience.
