Difficult to find a best located place in Lisbon, just in the city center. All public transportations are at hand and many touristic spots at walking distance. The apartment is very cozy and well distributed.
As being in one of the most populated streets in the center you need to cope with some outside noise, but street gets surprinsingly quite at night.
It has not elevator so when carryying heavy luggage it can be an issue. Other than that apartment fulfills short stay needs.
