I commend you for communication, but directions were poor and inaccurate. The "arrival guide" can be drastically improved; I understand that Lisbon is an old city that can be difficult to maneuver, but much can be done to ensure accurate arrivals--i.e. use landmarks, restaurant names, bodegas, etc.
As for accommodations, they were fitting, but not as cleanly as I hoped. I found many prior clients' hair, mold residue and even fecal substance. I'm not very picky, but cleanliness is an absolute must. I appreciate the assistance of Ana María as host, but I would've appreciated much greater attention to apartment appearance before our arrival, especially if you required a 4-night stay. It should've sufficed to have a very clean home.
