Our stay at Das Artes was average, It wasn't terrible but it wasn't the luxury 4 star stay you'd expect.
Most of the staff were pleasant and helpful, with good english skills.
Hotel a little tired and dated.
Our hotel room was unclean, there was a dried contact lens on the floor and dust on all surfaces. Bedside lamps didnt work. Bed was very comfortable though, and bed linen felt clean.
Room is large and spacious but with very little character. No sound from the halls or nearby lift which was a bonus.
Good range of english speaking tv channels.
Location was good, everything in Porto is a little spread out so everywhere is a good 10+ min walk. The area felt very safe even at night with a few cafes and a supermarket nearby. Hop on+off bus stop nearby.
Being a port town, the area is quite hilly, to reach the river front, it is a good 20min walk downhill.
