Alvaro's place was very big and comfy. There was a lot of space for a family of 4. The only thing that bothered me about the space was how the floor creaked anytime someone was walking around the apartment, which could be slightly annoying although mostly harmless.
The actual street of the building seemed to be difficult to find at first (it is a small street compared to the surrounding) , but the location is actually very central and literally around the corner from the metropol parasol (Las Setas de Sevilla). Right in front of the building is a carrefour express (a mini mart) which was very convenient as well.
Overall we had a comfortable stay here and would recommend this apartment to other travelers :)
