The apartment is ideally situated for exploring central Lisbon. The hosts are also very friendly and provided useful recommendations. There were however some issues with our stay which we were disappointed with.
The main issue - the bed. The bed is extremely hard and uncomfortable. We slept in it our first night and it gave us both a bad back (we are in our early 30s). We resorted to sleep in the living room after that, one of us on the chairs, the other on the sofa bed (our stay was 4 nights which should give you an idea how hard it is).
Some smaller issues:
We requested more towels and was told we could but for an additional €20. The fact we had a 4N stay and was only provided with 2 medium sized towels to shower with we didn’t think this was much to ask for.
The floor also has loose wooden panels, H+S accident waiting to happen..
Overall, good base for exploring a great city, but one of the few airbnbs that we have stayed in that we wouldn’t return to.
