We stayed for 5 nights and we loved it , the apartment is in a good location with a great view over the river to the statue that looks down over Lisbon.
There are a few flights of stairs to navigate to get to the accommodation but they got easier every day.
Check in was was easy and the hosts have put together a really useful information pack with advice of good eating and sites to visit.
Time out market is only a 10 minute walk down hill and there are many bars and restaurants at the top and bottom of the road.
Great apartment ,we would stay again
