Room was great, signs of wear & tear, but it was comfortable. I had almost everything I needed, except maybe a small trash bin for non-food waste. Shower stall was tiny (I had a bit of trouble getting in and out), but bathroom was well-equipped, with some hooks, a cupboard to place things on, and even a hairdryer.
I only saw Teo when I checked in, but he was always contactable and responsive. Communication wise, I depended a lot on Google Translate and hand gestures, but it was easy enough.
The house was mostly clean (except for the kitchen - might be due to other guests who had cooked and not cleaned up after themselves), in an extremely central location, and for a very attractive price.
Would definitely love to stay again if I'm ever in Barcelona! Thanks Teo!
