Carla was there promptly to meet us and get us settled. She had great tips for adventure and many to make it easier. If you're driving, Porto is a labyrinth of one way streets, so check with Marco and Carla for the easy way in. We made it just fine, so you should be able to as well. They even directed us to a most convenient and very inexpensive parking spot. Park it and forget it til you go.
The apartment is in the very heart of the city superbly located on a quiet street just off the square but central to all the sights, public transportation, and many walkabouts.
The apartment is very spacious, newly renovated, simply and tastefully decorated, very clean, complete, self-contained unit, and private. It backs onto a small private courtyard, so it's quiet and serene.
