There is nothing to improve. My parents and I were fond of this place. Thanks César for providing such a great place and also tips.
The apt was just as described, tastefully decorated and well located. When we first got in, the sofa bed was ready for sleeping since César knew there were three of us. Everything you need, towel, tissue, glass... all can be easily found and used. I would strongly recommend my friends to stay here when they visit Porto.
