Great apartment in the heart of Alfama, easy walking distance to some of the most beautiful miradouros and the castle. lots of little shops, cafes and restaurants around and easy access to trams 12 and 28, and metro in a few minutes walking distance.
The apartment itself is basic but has everything you need, would recommend max of 3 people though. I stayed there by myself for 3+ weeks and enjoyed my time there a lot.
Two negative points; the cleanliness was not great, when I arrived the bathroom was covered in mold, I asked the owner to take care of it and at first he wanted to charge me an extra cleaning fee (which I refused of course) and then he said he would send someone over the next week but that never happened. I ended up cleaning it myself, which I think is pretty ridiculous. Second thing I disliked was obviously the communication with the owner. He was friendly and would check in every now and then but whenever I pointed out something, like the mold or the fact that the vacuum cleaner had no pipe so was pretty useless, he did nothing to fix it. But now that re bathroom is clean, I would recommend for a short stay, mostly because of the great location ;)
