My colleague and I had a 5-night stay in São Domingos - Attic (4th floor) during a congress in Porto. The place was great, clean, renovated, with new and practical furnitures and fully equipped. The great advantage was the location of the building, in a very nice pedestrian street and close both to the river and the rest of the town, and especially easy to reach metro and bus stations. Our communication with the host was direct and quick before and during our staying. The two girls that waited us for the check-in (1.30am) were very polite and really willing to give us useful instructions for the city and places to visit. Definitely a good choice for staying in Porto, both in a good price and a perfect location!
