I strongly recommend staying at Alfama Sweethome 1! I have been traveling around Europe with 5 friends for the past few weeks and this has by far been the best accommodation that we have stayed in. There is plenty of space in the common areas as well as many beds that can comfortably sleep 6 people. Check in was very seamless and Jorge and his team are very responsive. The apartment was perfectly clean, and they left us some snacks that we were very grateful to enjoy after arriving hungry from travel! The amenities such as a washing machine and air conditioning all worked very well and made our stay quite enjoyable. It should be known that this apartment is on the 4th floor so certainly not for someone who cannot walk up that many stairs. Overall we had an amazing stay in Lisbon thanks to this accommodation and the recommendations provided to us at check in and would strongly suggest booking this apartment!
