We loved staying in this apartment in the center of Porto. It is very well located near to many good restaurants and shops. The check-in process was very smooth as both the building and apartment are accessed via key-codes. The apartment comfortably suits four people (two-couples). It's worth noting that upstairs there are two bedrooms with a shared bathroom and downstairs there is a half-bathroom (no shower/bath) conveniently located for the living-room/kitchen area. I would definitely stay again. AC was nice.
