We enjoyed our stay here. The apartment was clean and had all the basics we needed. We cooked many of our meals at home. Also, the internet worked without problems.
The best part was the location—within a very short walk you can be in Alfama or Graça, which were both really fun to explore. There's also a big flea market on Tuesdays/Saturdays right around the corner.
Liliana was friendly and responsive. She answered our questions quickly and gave good suggestions. Would recommend.
