Eli & Agus' place was perfect. It's centrally located, beautiful, and well-equipped for short stays or longer ones. The flat was modern & clean, and was the perfect size for our 4-person group with two bright, open bedrooms. High ceilings throughout and tons of natural light from the full-size doors in each bedroom made it feel open, airy, and comfortable. The kitchen is on the small side, but plenty well equipped for our needs, and the washer/dryer unit came in very handy during our week-long stay.
Our hosts were in close communication and left helpful recommendations in the flat for us (note–we went to all but one of the restaurants they recommended, and all were fantastic!). They made our stay enjoyable and stress-free, and we'd recommend staying in any of their listings without hesitation.
Overall, our Barcelona experience was incredible, thanks in no small part to Eli & Agus, and their fantastic flat in which we stayed.
