Lucia is a great host!
She gave me many tips for places to visit or where to eat in the area.
The place is really nice: quiet, view on the typical street, gardens and ocean.
It is near the Mercado of Ribeira and the metro station of Chiado and Cais do Sodré.
The famous Miradouro of Santa Catarina is just a few minutes walk away from the apartment and can allow you to have an outstanding view of Lisbon just after you have arrived!
Lucia is also really nice she allowed me to leave some luggage till late before I Leave for Coimbra.
I'll be back soon :)
