The location is beautiful with superb views and easy access walking across the bridge to Porto.
The place is adorable and clean. Marcelo was easy to work with.
There is only one shower, so 1.5 bathrooms. This place is best for two to four people. We would stay here again in a heartbeat.
You can walk down to the Gaia side of the river easily and visit the Port Wineries or have dinner and dessert.
We purchased the two day Yellow Bus hop on hop off which included the Douro River Cruise and the Calem Port Wine Tour which we recommend.
Once you see the city than walking is almost faster than the buses.
