Vitor met us at the apartment and showed us around when we arrived. He made it clear that we could contact him for any questions about Lisbon or any problems with the apartment, although we didn't need anything in the end.
It's an authentic little apartment on a narrow windy street, but quite modern inside and had everything we needed, including shower gel and shampoo. It's close to the Castle and has easy access to the Metro; it's quite easy to walk from here to most places within central Lisbon but it is hilly!
A great stay, all in all.
