What a great place! We loved our time in Barcelona and a big part of that was the wonderful location in a fantastic 200 year old building. The building was old, but not the apartment! Everything was first class and modern. And they had everything we needed for a great stay--quality linens, a fully-equipped kitchen (including coffee), and a cute little balcony to sit out and watch the activity.
Monica and her brother were great hosts--always there to answer questions or work with us when our plans changed (which they did, multiple times). This was my best Airbnb experience ever, and I've rented a LOT! I'm also a host, so not always easy to please. I highly recommend this rental.
