Cristina's apartment is superbly located. It is very central but a street away from the bustle of Rua da Flores. The view from the balcony is unbeatable and you can enjoy your breakfast in the sunshine watching the cats on the roofs below. The studio is in an old building but very modern inside, super clean and comfortable with everything you could need. If a good shower and sound mattress are what you are looking for this is the right place for you. Cristina is a very helpful host. One thing to know about Porto is that it is buzzing at the moment which is brilliant but means that there is a lot of restoration and construction in the old town. Don't be surprised to see by this and it won't spoil your visit to this gorgeous place.
