We went to Barcelona for a quick weekend trip, and were looking for something convenient and not too expensive. Francesco's place was great.
He was at the apartment when we arrived, and showed us everything. He was very friendly, and it was easy to communicate with him whenever we needed to. He was also flexible about a slightly later checkout time.
The apartment had everything we needed for a few days. It has a subway and a train station nearby, but we mostly walked everywhere.
One thing to note is that the apartment is on a small street that most people haven't heard of. Every cab driver had to look it up. One night we were nearby and only had the exact address, and no one could give us directions. I would note the cross streets nearby.
