This is a very nice apartment. It's air conditioned, the beds are extremely comfortable, the lounge is a good size (and comes with its own Play Station) and the second bedroom is on a mezzanine at the far end of the apartment so the kids can go off and be on their own and give you all the peace and quiet you want at the end of a long and tiring day - and days out in Lisbon are usually long and tiring.
There is a mini-supermarket directly below the apartment, several bakeries within a hundred metres in either direction and so many restaurants within a five minute walk that you'll be spoilt for choice. Also, there's a plaza just down from the apartment and the Museo do Fado is just opposite, so it makes arranging taxi or Uber pick-ups or drop-offs incredibly convenient.
I would definitely recommend this place to anyone looking for a convenient base from which to explore Lisbon, and I would definitely recommend exploring Lisbon.
