Mirella is a great host. The place is quiet and has almost everything you need (no regular oven, only microwave). The sofa is not so comfy but who is watching TV while in Barcelona? The place is on walking distance from attractions like Sagrada Família and Park Güell. Be aware that there are elevators from the lower street to the level where the building is. Make sure you know a bit of Spanish and/or Italian to fully communicate with Mirella.
