Really nice apartment in the old part of city. You feel that original vibe.
Room is clean and bright. Really enough to stay for one week or even more. There is enough space in the kitchen and there are two toilet rooms, so it's not a problem to share space with other guests.
As Luis wrote, street is pretty noisy, so it's better to have ear plugs. But Teresa even bought them for us by herself.
You can also reach Rossio and Cais-do-Sodre train stations 10 minutes by walk easily to go to Sintra or Cascais.
Teresa met us even in the night, because we had late flight.
And the whole stay was warm and pleasant. Really recommend this apartment.
