Tirso & Noemi place was exactly as described -- clean, spacious, and close to public transportation and establishments. Having two rooms were great for me and my parents, bec. that means I have some privacy for myself.
Just a note though: The smaller room is not fully separated from the living room. There are two "windows" on top to allow the air from the living room window to flow into the small room. That makes the room sufficiently aired and thus cool during the early September nights. Unfortunately, that means it is not fully private and I could hear conversations and the TV from the living room.
But everything else was great for our needs and short stay. Tirso and Noemi were also very kind to help us deal with our washing problems. One even came to help us do our laundry when we could not figure out how to make the washing machine work! They also entertained our questions and were easy to communicate with through Airbnb and Whatsapp.
Thanks a lot and will definitely consider staying at your place again when we return to Barcelona!
