Maria Teresa's appartment is perfect to discover and enjoy Sevilla. The area of Triana is great with a lot of flamencos tabernas and nice bars where to eat good tapas. It's well located, close to the Guadalquivir. You just need to cross a bridge to be in the city center and you are walking distance to the main touristic spots. The flat is well equiped and simply decorated. It feels like home. It's a bit dark inside but we were travelling there in January and weather was not that great so I'm sure it's better in summer time.
Maria Teresa is a nice host. It's easy to communicate with her and to arrange arrival. She let us stay later on our last day considering that there were no other guest coming. I recommend this place.
