The apartment was clean, comfortable, quiet and very well equipped. The location is very convenient to the Sants train station and the major Barcelona attractions. It's within a few blocks of Tarragona, Entenca, and Plaza Espanya Metro stations, from which the Metro lines will take you most anywhere. At Plaza Espanya, bus 150 takes you to beautiful Montjuic.
Roberto is an outstanding host. He stays in touch before and during your stay.
The place is very well equipped, with plenty of towels, hangers, good toilet paper, clean pots, pans, utensils, soap, bath supplies, dishwashing supplies, and other details that vacation rentals sometimes lack. Roberto is very good at anticipating your needs.
The only thing that stops me from a five-star rating is that the bathroom in our unit - no. 10 - was TINY, even by European standards. If you are small, the lack of room may not bother you, but if you're tall or big, you won't fit. My wife was okay, but I had to dress in the kitchen.
