I loved my stay in Jazz's apartment, I can't find any fault with the apartment itself. The location is right in the middle of Chiado (one of Lisbon's most charming areas). It's very central and located close to all major transport lines and Lisbon's major attractions. In terms of the apartment itself, It is newly refurbished and has lovely modern finishings throughout the rooms - the place itself is very secure and safe.
It was easy to communicate with Jazz and she is always checking in on you during your stay, providing tips, etc. The check-in and check out procedure is very straight forward with the keys being in a lockbox for easy access.
I would recommend this apartment to couples or solo travels coming to Lisbon for both business and leisure. Thank you once again Jazz!
