The appartment is very clean and has a very good shower. The airco did not yet have to do its work (visiting time: March). Yes, you can hear the traffic on the main road close by, but not enough to keep me awake.
I selected the appartment mainly because of its location being outside of Sevilla's main tourist areas. It can easily be reached by bus (1,3,6,10,14, all within immediate walking distance), but the 20-30 minute walk to and from the city center alongside the river is also nice.
Montserrat is friendly; my Spanish was just good enough to understand her advice. It was heartwarming to see her mother is well taken care of.
