Location is convenient but noisy. Barrio alto is very romantic and has awesome stores and bars, but it is a party zone. Nonetheless, people drinking in the streets wasn’t the problem, but a construction inside the building (ongoing until September 2019), so don’t expect to sleep past 8:30 am.
To compensate for the banging and drilling I can say that the bed linen was comfortable and overall the apartment was well suited to host a family.
The recommendations in the instructions booklet were outstanding. We visited a couple of the restaurants suggested by the host.
On the negative side, there was a strong sewage odor in the bathroom. This was constant through our stay and made it unpleasant. Also bring soap, shampoo, and toilet paper. I found none.
Lisbon is so beautiful that our overall experience was positive but I think that the owner needs to put more attention to details or inform about the above mentioned issues.
