Carlos and Christina's apartment is located in the old port area which is where you want to be when first visiting Porto. The apartment is a studio with 2 large windows that brighten the room during the day and offer a fresh breeze when open, perfect. The room is well equipped and very modern. The bathroom is modern and very nice with good water pressure for the shower with lots of hot water. The bed is very comfortable and we had 4 good nights sleep while there.
There is a modern laundromat 100 ft of the room and more restaurants than you can imagine within a 15 minute walk.
If you have never been to Porto be forewarned that walking up and down hills is inevitable and most are very steep. Probably why most of the citizens are in such good shape, but we are in our 60's and we managed quite well.
