Great location, best to arrive by taxi which was a 20-22 minutes ride for us in the middle of the day (approximately 14 euros depending on when you arrive or leave) since uber cannot enter the residential zone that the taxi is able to (this means the taxi drops you off at the door whereas the uber drops you off at the bottom of a giant hill). When you depart just wheel your bags down the hill (gravity will surely help with that) and can easily catch a taxi back to the airport. About a 5 minutes walk to Time Out Market that closes late. Tram and buses at the bottom of the hill were very convenient. And walking distance to Metro stop as well.
The amenities are great. No street noise at night since the rooms are set in the back of the flat. TV has English channels (we watched a ton of Hawaii Five-O lol). Water pressure for the shower is wonderful.
If we ever come back to Lisbon again this surely will be the place.
