The appartement looks nice on the pictures but in real life it is truly amazing. It is quite spacious and you feel the effort made in decorating it with style.
Location is fantastic because you can walk to the city center and it is close to the subway, so you have fast connection to public transport and train if you want to go outside Lissabon.
There are some minor details, like leaking water from the shower, there is a café just next to your bedroom so sleeping with open window is not an option, but windows closed works perfectly fine. The acoustics on the street are like at the opera. It gets a bit smelly outside in the summer so it is best to keep the bedroom windows closed and open other windows if you want a fresh air. Also mind you neighbor with the noise, he is very sensitive.
Other than that it is absolutely great, we had an amazing stay. The neighbourhood is full with great restaurants (especially seafood, lobster, oysters!) and Lidl supermarket is just around the corner so you can have fresh pastries for breakfast with some espresso and go to explore the city.
