I stayed in a room with a single bed (number 1). It was exactly what I needed: just a simple and clean room to spend a few days in Sevilla. It's pretty much what you see on the pictures. It was nothing fancy, but for the price, it was clean, modern, comfortable and very quiet. The room is small but perfect for one person (given I would only spend a few hours there to sleep). The common area is nice too: there is a fridge, a kettle, a coffee machine, some plates, glasses, cuttlery... Just what you need for a quick breakfast or snack before heading to the centre of gorgeous Sevilla! Be aware that there is only one bathroom (and toilet) for 4 rooms, so anticipate for your shower.
The neighbourhood is also nice = Triana. It's a pleasant 20-min-walk to the major attracations of Sevilla.
I would definitely recommend this place to anyone coming for a few days!
