Rachel's place was so cute, and her dog was even cuter. She was so patient while I made my way to her place at such a late hour (flight got in at night, issues with luggage). Definitely consider this place if you have a backpack or a duffel bag. The building's staircase is very narrow, so I could see it being very difficult to bring up a big suitcase.
A 20 min walk to downtown, and super close to the metro (~5 min walk). It's even close to a scenic lookout called Miradouro da Senhora do Monte, just a 10 min walk up from Rachel's place. If you have an overnight layover and you'd like to explore Lisbon for a few hours in the morning, this place is perfect. Obrigada Rachel!
