This is a very nice space! We enjoyed having our own bathroom and bedroom with a very comfy bed; and sharing the well-stocked kitchen, dining and living areas with Tadaaki and Danko-Dog (Ron was out of town at the time of our visit). Tadaaki prepared delicious and beautiful breakfasts including homemade jams and bread, yogurt, fruit and cheese, coffee and/or tea. Coffee or tea were provided for us to make any time we wanted, and we did a load of laundry for no extra charge.
Location is excellent, right in the middle of shopping and eating areas, close to Las Ramblas and the Cathedral, Placa Catalunya, and easy to get to several different metro stations. Ron and Tadaaki provided a binder with helpful recommendations and descriptions of various activities and restaurants, and Tadaaki added more information and insights in person.
All in all, this is a wonderful place to stay, with good people (and dog).
