I simply do not think my expectations could have been any more fulfilled; the flat is beautiful, centrally located, has a wonderful local restaurants and markets within walking distance, and is a quick jump to the metro.
The host met us with a smile, gave us a quick tour, and then respected our stay and use of the flat for the full five days. The amenities were flawless, the beds are comfortable, and the showers have me remodeling my place back in the States.
This flat is a treasure in Barcelona; the next time I am in Spain, I will be looking to stay here.
