we stayed two nights in the small but excellent and newly renovated ORM accommodation. we had a hearty welcome with good tips what we could see in the city and where we could have nice food. the location is really good. the city center and all interesting spots are located within walking distance. at a corner close by is also a really nice bar, where you can have good coffee in the morning and proto tonic in the evening. you should definitely try it! all this together contributed to wonderful memories of our stay in porto.
