This is a gem and a great find!
Check in: my friend and I arrived at different times and accommodations were made. In addition, Joseph made effort to be able to greet both of us when we arrived and tried to see us off when leaving.
Accommodation: the sheets were soft, blanket was warm and fluffy, and there were multiple pillows to choose from. We were able to use the fridge, a basket for dry goods, and use of the kitchen. The shared spaces were cleaned on a daily basis. Please note that you are in the heart of the gothic quarter (walking distance to a lot of attractions), as such there is some ambiance noise on weekends. I was fine and slept well but if you are a light sleeper you may want to bring ear plugs.
Special touches: the room theme was nautical and fun. There was also drinks (water, sparkling wine, non-alcoholic drinks) upon arrival. He was also able to recommend places to eat and see which were very good.
Overall great value for money and would definitely recommend staying here, awesome location for Barcelona!
