Priscilia's apartment is a great choice for exploring the city of Lisbon as it is directly in the heart. Located next to the rossio station what gives you a good connection to the public transportion (airport, Cascais, Sintra, etc...).
The apartment is exactly how described. It has a great size for 2 persons. A well equipped kitchen with everything what you need. Priscilia has a flyer with some recommendations and tips for restaurants, bars etc... Different travel guides are in the place and it is clean and very comfy.
Last but not least...
Priscilia is a wonderful host. Helpful and quick in answering - essential things for travellers.
Summed up - if you want to explore the city, this place is a great choice.
It is really central and lively...
When you need silence afterdark maybe another option would be better. Lisbon is going late to bed. That's for sure ;)
