Overall a very pleasant stay. The apartment lacks a living room so I'd recommend two max in this otherwise charming flat. The kitchen was a bit small and hard to make space, but Lisbon has so many affordable eating options this wasn't too big of a deal. Since it's on the ground floor you can get some street noise but with the air conditioning on and windows closed this isn't too much of a problem. Otherwise, a very pleasant stay and located centrally to many bars, restaurants and some main sights. It's up on a hill so I'd recommend uber/transit if you're not used to walking the hills of Lisbon. I didn't mind at all as I always discovered a new interesting route back! About a 20 minute walk to Rossio. I'd definitely stay here again the next time I'm in town.
