This was a wonderful place to spend a month! Wi-Fi worked great so we were able to easily work remotely. We loved the location so much and public transit is so convenient (numerous bus lines out front and a metro/train station 8 minute walk). The best places for sunset are all just a short walk away and there are restaurants and markets all over the place so you can find everything you need within 10 minutes walk. Alfama is amazing - I would never stay anywhere else! It's pretty incredible to be living in old Lisbon among the iconic colorful buildings and there are bars, fado restaurants and very cheap, local Portuguese food all over the place. Alice and Mike were really great hosts. They were flexible about a friend picking up our key for us since we missed the check in time and they checked in on us a few times during our stay. They used to live here so it feels like a nice home and has nearly everything you need (we had no way to listen to music but luckily had portable speakers with us).
My only complaint is that it's an old building and noise travels easily. I am a very light sleeper so this part of the review is for others with the same problem. The other reviews are correct that the buses that go by shake the room and bed. They don't run all night, but they do run pretty late and start again early morning- that said, this shaking never woke me up from sleep. However, there are neighbors in the building and the insulation isn't great (or non-existent you might say). For me it was a problem and did affect my sleep - though my roommate didn't mind and sleeps heavier. If you sleep well, it shouldn't be an issue for you, but if you struggle with noise, this might not be the best choice.
