To avoid scams when looking for student accommodation Lisbon, always use reputable websites and services. Avoid listings that require upfront payments without a contract or viewing the property. Be wary of deals that seem too good to be true. Verify the landlord or agency’s credentials and read reviews from previous tenants. It's also advisable to visit the property in person or arrange a virtual tour before making any commitments. Trust your instincts and seek advice from university housing services if needed.
