Teo's house is in the really center position, just next to the La Rambla. It's not by the street, but in the small path next to the main street; therefore, it's quiet, away from the noisy bars or restaurants.
From this house, you can get to any places of interest within 30min by the public transportation or on foot. Yes, on foot. my friend and I didn't even buy the 10-time ticket because we found walking in the old town is really interesting.
Teo lives in the same house with us. The room he provides us is not that big, but really cozy. If anyone wants to feel the gothic area and the old Barcelona, Teo's house should be a great choice for you.
