Cristina's place is very comfortably located so that it is possible to explore all the sights of Porto. If you have a rental it also is quite easy to find a parking space nearby- or we have been very lucky?
The bed is very comfortable and the kitchen and bathroom were very clean.
wi-fi was available, as was a coffeemachine with some capsules so that you did not have to worry about your first coffee after arrival. There also is tea, basic spices and dish washing liquid.
I would definitely stay here again. Porto is a wonderful city and it is worth being visited more than just once.
