Cesar's place was absolutely perfect. The location is close enough to the center of Porto, and close enough to the metro and the bus, but on a very quiet street. The studio is big enough for 2 people to be comfortable, and it was immaculately clean. The bed was extremely comfortable and Cesar & Carmen have thought of every possible thing a guest could need. On top of all of that, Cesar was very very nice, and they have a big book of recommendations of places to visit. If we ever come back to Porto we would definitely stay here again.
