Joana was a great host, she sent us all the information we needed prior to our arrival in Lisbon, from how to get to the apartment from the airport to the wifi password. She was always in touch and willing to help.
Regarding the apartment, although its facade looks a bit old (which has its charm), the apartment is quite modern in the inside and everything looks new. It has a tv, a Nespresso machine, ... All you need is there.
There are plenty of options to eat and party around the area. Which can be a bit noisy in the morning but we didn't go to Lisbon to sleep B-)
