We stayed at Cristiana's apartment for four nights, but we didn't have a chance of meating her. Never the less, she organized a check in with a friend of hers and everything went well. Cristiana's apartment was perfectly clean, cozy, and nicely furnitured. We had everything we needed, since the kitchen was well equipped. There is a beautiful terasse which gives a nice view and is great for morning coffee or a dinner. Communication with Cristiana was perfect, as well. If we ever stumble upon Porto again, I'm sure this apartment will be our home.
