The appartment is big enough for 2 persons, clean and offers everything you need during your stay. We were there for 1 week. It's close to metro station Santa Apolonia and many buses, so very easy to get around. It's easy and cheap (€ 1,50) to use the metro to get from/to the airport in only 45 minutes. Digital communication with Benjamin was fast and easy, self-checkin and out too. We specifically choose Alfama because it was said to be a quiet area/neighbourhood, however we did have trouble sleeping because of the noise. The garbage cans get emptied at midnight, which means there's a lot of noise from the bins getting wheeled over the cobble stones, same for people with suitcases that walk by. Also the walls and floors of the building are very thin, so you hear every step of the upstairs neighbours, which sounds more like stomping. You hear every person that enters and leaves the building (talking, taking the stairs, but also loud doors and door-locks), which might wake you up, even if they try to be discreet and quiet. We had some trouble with the shower water staying warm after one of us showered, but I think that's common in some countries. So be quick! We can confirm that we slept comfortably on the convertible sofa, it has a thin mattress topper and we had no issues. However for us personally, the pillows were too soft, we used the decorational pillows to put under them for a little more support. Overall we would recommend this apartment and it's convenient location, but maybe bring some earplugs to sleep.
