Marta's unit is fantastically situated near major tourist attractions and metro line; yet it is just far enough away that you will find lots of neighborhood gems and local hangouts. The unit has room to work (and with good wifi to boot), cook, and lounge around.
Throughout the experience, Marta had been very hospitable and accommodating, even when the airlines threw a wrench in our travel plans. Marta's husband, Xavier, greeted us personally and made sure that we got the most out of our stay - thank you!
I would definitely consider staying here again next time we're in Barcelona.
