This property is phenomenal. The view from the apartments facing the river and the patio is much, much better than shown in these pictures. You really have to be there to appreciate the view. The apartments are well furnished and clean. The kitchen has everything you need for a short stay. We rented the entire property for a big party of 14 people, but if you are only renting one of the apartments, #2 has a beautiful terrace and the best views of the bridge. #7 also has a great view and a smaller patio.
Getting to and from the Casa Golgota can be a bit tricky, since you can only access the property by foot through a granite stone-step street. Also, the house is located at the end of a street (Rua de Bom Viagem), which is another steep hill. The steps and the hill could be a bit difficult for people with knee or back problems, and you will have to carry your bags as well, so make sure you are comfortable with the climb. The house is very well located just a short 20-minute walk (5 minute car ride) to the old town. The neighborhood seems a bit sketchy, but the streets are well lit at night and Porto is a very safe city. Just make sure to be aware of your surroundings when you are walking at night or alone (which, as a tourist, you should always do anyway).
Marcos is an excellent host. He was very responsive during our stay and came several times to fix some small issues around the house. He also gave us great advice regarding restaurants and places to go.
I highly recommend this property to anyone traveling to Porto!
