David is a good host, who gives you all of his attention when it comes to making sure that you are educated enough on Barcelona and where to go and how to stay safe.
The big issue is that the apartment doesn't look nearly as clean as it does in the pictures. There was dust and grime in almost every room and black mold in the bathroom. I think a thorough deep clean of the bathroom and kitchen would actually make this place stand out above the rest. The cleanliness is the only comfort factor that needs major improvement.
