Cristina's apartment is very nice, looks exactly as shown in pictures and is fully equipped with everything you might need.
Cristina was a great host, she welcomed us in the apartment and provided us with many useful tips about thing to do and places to eat in Porto.
The only downside for us was the absence of air conditioner - unfortunately, the week we spent in Portugal the weather was extremely hot, the temperature reaching 40C during the day, and dropping barely below 30C at night - so it was a blazing heat, particularly in the bedroom (which has no windows). But, we were told that this weather is very unusual, so, normally, the apartment would be nice and cool, especially in the evening.
Overall, aside from the weather, we had a great time in Porto!
