We never met Adelaide or Paulo in person but everything went smoothly regardless.
The apartment was clean, well equipped kind of small but it was alright if you just need a place to crash and spend the rest of the day exploring Lisbon.
The bathroom is very small, even I as a medium sized person had some trouble in the shower, my elbows constantly hitting either the wall or the glass door.
The bed was great and the sheets very clean, soft and comfy.
The location is very central, in a back alley in Alfama which is a relatively dirty and loud neighborhood. We never had issues with the street sounds however, the windows are doing a good job. We heard the neighbors though, quite often, it seems the sound isolation is not the best.
All in all, it is a great apartment at a great location if you mainly need it to just get a night's sleep. It may be too small if you want to do more though.
From our perspective, we highly recommend it.
