To repeat a lot of the reviews here, this apartment is a very good base if you just want somewhere to sleep and house your things while you explore the city. It is very basic, there is only one cup for coffee or tea for example! There is enough for you to be able to cook a basic meal though.
The location is perfect for getting around, close to transport, and walkable in relation to many other places. It was lovely to feel like we were in such an old and authentic part of Lisbon too. It was lovely to have such a beautiful place right on The doorstep.
The Fado restaurant below was quite loud, although generally quiet past midnight, we liked the music but if you're a light and early sleeper it would probably be an issue... Also it's quite easy to hear the neighbours staying in the other apartments, however as it's an old building it's to be expected.
The bed was fairly comfortable and the shower was a good pressure, though the hot water didn't last more than ten mins, but again, it's in an old building.
Katy was very good communicating with us, quick to reply and easy to arrange things with. The check in and check out process' were smooth, we received some tasty pastel de nata upon arrival too which was really sweet.
Overall we enjoyed our stay, we loved Lisbon, the apartment was in a wonderful location and it was a great base to have with the basic amenities.
