Location for this apartment is great. 5 minutes walk from either Placa de Commercio and 5 minutes from the next metro station and shopping mall. This is ideal for visiting Lisbon's historical center as well as catching a train to Sintra or Caicas. Also about 10 minutes from Time Out Market.
We were 2 people in the apartment and it was really comfortable. Decorated with attention, practical and higly liveable.

The owners are really nice, kind and helpful. We will not forget the welcome gift! They spent a lot of time sharing info about the city with us.

The main bad point is that there is no lift (apartment is on the third floor). It was not an issue for us as the owners where there to help us lift our suitcases on day one. However, I don't think it was mentioned on the apartment description. This place is not for people who have difficulties to walk, as it is also located in a pretty steep street (as are most streets in Lisbon).

The other point it the tram noise, as the tram is passing by the building. Again, not really an issue as the noise is not loud but good to know in advance.

All in all, highly recommended for discovering Lisbon.
