Studio59 is a wonderful place to stay: great air conditioning (important during the heat wave!), comfortable, clean, and well located. The arrangement is interesting: a set of studio apartments, accessed first by a door into a common hallway, and then doors into each studio. The first door, into the common hallway, has a keypad lock that is tricky until you get the hang of it. Pedro, the host, responds very promptly to any questions or concerns. We would happily book Studio59 again next time we are in Lisboa.
