Maria's place is a lovely home. The weather in Seville was unusually cold and very wet during our stay, so it was really nice to return from our sight seeing to a cosy place with a well equipped kitchen and a comfy bed.
The flat is located close to a big supermarket and shopping mall. We did walk into the centre on our first day, when it wasn't raining, but it does take about 45 minutes. Thankfully, Maria gave us a bus pass which we used on other days and the buses are frequent and easy to use.
