Once you make it up the four flights of stairs and through 3 tricky doors, this apartment is gorgeous and extremely clean. Try to arrive during the day if you can because there is a timer on the hall lights which shuts off by the time you get to the top floor with luggage. Small square buttons located on each level will turn the lights back on but be careful because the other wall buttons are door buzzers and neither type of button is labeled. We found a great little bar nearby called Klg Café Estúdio. It was so welcoming and were able to enjoy a great variety of food and drinks even late at night.
Currently there is massive construction going on next-door which begins at 8am and often means the street is blocked. This got us up early every day and meant we had to hike with our luggage to meet our taxi when leaving. Neither were a deal breaker but it would have been nice to know in advance since sleeping in was impossible.
The hilly geography of Lisbon makes navigating challenging but once we made it to the nearest metro station to buy reusable passes, things got way easier. Quick note: While the passes are reusable, they are only rechargeable for the type of service you originally purchased.
3 days wasn't enough time, we'll be back Lisbon!
