Tenants typically pay no agency commission — the broker fee is charged to the landlord.
Furnished and equipped-kitchen rentals are widely available, and listings clearly flag mobilado vs sem mobília.
Universal, predominantly tax-financed public system (SNS) covering the whole resident population, with GPs as gatekeepers to specialist care
Most public care has been free of user fees (taxas moderadoras) since 1 June 2022, including health-centre consultations and prescribed exams

Watch out for

Up-front cash is high: a security deposit (commonly one to two months' rent, occasionally more in high-demand areas) plus often rent paid in advance (up to three months is legally permitted if stated in the contract).
There is no legal cap on the deposit and no mandatory escrow — the landlord usually holds it directly, so document the property's condition to avoid move-out disputes.
To be registered with the SNS and have costs covered you generally need legal residence: a valid residence permit, a Portuguese tax number (NIF) and a full local address; an SNS user number alone does not guarantee cost coverage
Short-stay visitors and nomads without legal residence normally cannot rely on the public system for covered care and use private insurance (or an EHIC for eligible EU visitors, who claim any reimbursement after returning home)
