If you’re a single person staying in Lisbon for a short time, you might not dislike this place. It’s tiny but in a fantastic location. It’s not the cleanest, but if that’s not a dealbreaker for you then you’ll be fine with this place.
If you have young kids that require holding and a stroller or something of the like, don’t stay here. The stairwell is narrow, very steep, and pretty dark making it really difficult, if not impossible, to navigate carrying a little one, luggage, stroller, etc. And as I mentioned, this place is tiny so be prepared to share the small bed with your baby. The one saving grace was the couch, which was actually comfy and got a lot of use since my spouse and I had to trade off sleeping in it while the other made sure the baby was secure on the bed. Suffice it to say, not a lot of sleep was had.
The neighborhood is quite great, though. Lots of great little restaurants and shops. Very much recommend the area!
