Ana is very friendly, welcoming, and helpful. The room has plenty of space, lighting options, a very nice desk, and comfortable twin bed, directly connected to the rest of the apartment. Ana keeps the room and bathroom VERY clean, I was very impressed. It worked perfectly well for my needs.
The location is very convenient, near a metro station and plenty of little cafes. The only thing I would say to prepare for is the summer heat in Barcelona --- coming from places with central air in the US, I definitely missed that on my trip. This is a common "issue" throughout the city, many places have ceiling or wall AC units (such as this listing), but they don't spread the cool air around nearly as well.
Each day, I had a nice morning walk up to the university for a conference, and Ana helped provide tips and suggestions on sights to see both in and out of the city and what to watch out for in touristy areas and on public transit. Overall, I would definitely recommend this place if you are visiting Barcelona.
