We enjoyed our stay at Mònica’s place. The location is great, and we walked to all the main places we wanted to go. (La Sagrada Familia, La Rambla) There are also many yummy restaurants within a 5 minute walk of the apartment, and we enjoyed exploring the side streets and shops in the neighborhood.
The space is well done and newly renovated with a full kitchen, and comfortable, clean bathroom. The living room and bedrooms are a bit small, but arranged with thoughtful layouts that make them quite cozy.
Our hosts were also very accommodating of us as we were traveling with a baby. They provided an infant bed and chair for our stay, and allowed us to store our bags in the apartment on our last day after check out. The only downside of this apartment for a family is that it is on the American equivalent of a 5th floor and, while there is an elevator, it was smaller so it sometimes took us more than one trip with our baby, stroller, bags, etc.
Overall, we would highly recommend this apartment and would choose to stay here again for another trip to Barcelona.
