Wow! What an incredible place to stay! The apartment is huge - very suitable for a large family - or for a smaller group who just needs to use one or two of the bedrooms. The host, Joao, is wonderful: great communication, kind and very helpful. When we arrived, he had provided some fruit and bread rolls - what a thoughtful, kind thing to do. The kitchen is very well fitted out.
Perfect location: a 15-20 minute walk to the Dom Luis Bridge and the river, and there is a tram stop right outside that takes you to the old quarter.
Note for other guests: We used G Maps to locate the apartment but kept missing the last stage of the directions. It turns out that the entrance is a driveway to an underground garage - with a parking for the guests of the apartment. So, if you are driving there and you're using G Maps, look out for the tram station directly opposite the driveway. It's called Camara Gaia - turn into the driveway there.
