Susana's apartment is very clean, comfortable and well-located. We could easily find it when we took the local C4 bus from the Plaza de Armas bus station. It is also easily walkable to most of the interesting sights such as the Alcazar, the Cathedral, Santa Cruz, Plaza Espana, etc.
Communications with Susana was a breeze and she (with her adorable son Pablo) was at the apartment to check us in. She took the trouble to mark out 4 different walking tour routes on a map for us including supermarkets and places to eat. There was also yummy muffins and sweets left for us..thank you, Susana!
We felt safe walking around the area, even at night. As we were there during Christmas, there was a big Christmas market nearby on the way to Plaza Espana.
Seville is truly magical during Christmas and I highly recommend Susana's apartment!
