We had a lovely stay in Tomas apartment. It is very well located:
2 mins from Alcazar
2 mins to catherdral
20-30mins walk to Plaza de Espana.
The apartment is tucked away on a side street so is nice and quiet. It is also nice and cool in summer and has air conditioning, which is a real plus in seville.
The courtyard is prettier than in the photos.
The bathroom and kitchen are a little dated but were clean and functional and nice to have a separate kitchen.
The beds were comfortable. The apartment is a good size for 2 people.
