I stayed at Sofia's place with my husband and 2 sons, ages 5 and 9. Her place was a perfect place for our family. It was clean and comfortable with everything we needed to feel like home.
Sofia was a wonderful host! She was quick to respond when we had questions, and was very friendly.
The apartment is within walking distance of serval restaurants and small grocery stores. There are 2 metro stations that we could walk to in less than 10 minutes. The walk to Sagrada Familia was a bit longer, but mostly downhill so we could easily manage it even with the kids.
