The place was very spacious for what my friend I needed, but there were a few issues with poor communication and a very preemptive attempt to charge me for a late check-in fee (a week before my arrival - and we did not arrive late). Check-in was a bit messy because Uber's don't arrive on that street at that location so there is some walking with bags involved.
If you are looking for the crazy drinking/drugs clubs scene (we were not), the unit is located right above a BUSY bar and street of bars so the noise goes until 3am each night. Few flights of narrow stairs to carry heavy bags up so beware of that. Smell of cigarette smoke fills the unit due to the aforementioned street/bars below.
The kitchen is spacious and inviting with all the appliances one might need. The main bedroom is quite nice as is the bathroom. The other bathroom is fine but small. Henrique, Maria's boots on the ground help, is quite polite, helpful at recommending tourist activities, and is the main point of contact for check in and check out. Five stars for him. The overall location in Lisboa is also quite good - was able to make morning runs to the port or to one of the many miradouros (Miradouro de São Pedro de Alcântara) for that lovely Lisboa sunrise.
