The stay itself was fine, but the check-in process was the worst we have experienced in over 30+ years of travel.
Numa's automated passport verification system rejected two of our three passports without explanation, even though the same images had been accepted elsewhere during our trip. Once rejected, the system would not allow another upload attempt. We were on a cruise at the time and did not have physical access to our passports, making Numa's demands for new images extremely difficult.
For four days I tried to complete check-in. Support responses were slow and repeatedly told us to "try again," despite the fact that their system made that impossible. We were sent an alternate upload link that claimed PDFs were accepted, only to discover they were not. The entire process was bureaucratic, inconsistent, and created serious concern that we might arrive in Lisbon without access to our fully prepaid accommodation.
The problems continued after check-in. Numa initially gave us the wrong room number, resulting in multiple failed entry attempts before support acknowledged their mistake and provided the correct room.
The rooms were clean, comfortable, and well stocked. However, the customer service, communication, and check-in procedures were extraordinarily poor. We felt treated more like a security problem than paying guests.
Because of this experience, we will never stay at another Numa property and cannot recommend them to other travelers.
