We stayed at Rocio's place for four days just before christmas and during christmas. The flat is in a good condition and has all the equipment needed for basic cooking. It is EXTREMELY well located (at 10 meters from the Triana market)!!! and just next to the bridge to go to Sevilla centre. At first, I was concerned about crossing a bridge by night with my girlfriend, but the area is really safe and we never encountered any problems. The communication with Rocio was fluid and, although she was not there when we arrived, her father showed us the premises. In general, both persons were extremely responsive and attentive to all our questions. There is a super fast wifi connection in the flat too.

On the downside, the flat can be noisy by night when people pass by the callejon next to the apartment.
I would recommend staying at this place for a short stay in Sevilla.
