As the other reviews will state, this is a fantastic find in the heart of Barcelona. We found the place to be located on a wonderfully quiet private drive in the heart of Barcelona. A super safe place to stay, and you're no more than a block from groceries, bakeries, coffee shops, and restaurants.
Marta & Cesc were friendly and highly responsive, and made checking in early a breeze for my (non-frequent traveler) mother who arrived a day before we did. We had our baby with us, and they provided a clean and fantastic crib, toys, dishware, and high chair to use, saving us plenty of packing headaches. The whole place is quite child-friendly, too.
The place was well-appointed and extremely hotel-like, with great linens and an absolutely spotless cleaning prior to our arrival. The terrace on the top floor is large, quiet, and comfortable, and a wonderful place to relax in the shade or sun (thanks to the massive retractable awning) day or night.
With four bedrooms (one is upstairs, either take the stairs or the private elevator- very private and great for a couple) and two well-appointed full baths, plus a full kitchen with plenty of coffee options (which we loved), you're in great shape here, and we won't hesitate to return the next time we go back to Barcelona.
