As others have shared about Dulce's friendly spirit (she is the keeper of the grand house)! It's all true! You can depend on her for anything!
Know that the house is situated on an incline (not difficult for ambulatory folk), about 3 mins from the main boulevard of Travessera de Dalt—which, within a 10 min walk, has all the transit you will need. You will need to use transit to get to anything a tourist might want to experience (Walking from Pza Catalunya takes at least 50 minutes—trust me!). For a week in Barcelona, I purchased the "Casual" ticket at the station (which has easily understood explanations in English, Spanish, Catalunyan).
As is described in the "What to Expect" section, the rooms are spartan and not heated. The fuzzy electric blanket was heavenly tho'. ;-)
I had no hot water twice until I alerted Dulce, who responded immediately.
I was here in late November and the mornings became uncomfortable. I'm sure summer is wonderful though!
Barcelona es tan bellisima!
