We had a 14 hours layover in Lisbon; therefore, need to stay here for one night. The service apartment was very close the main street with a lot restaurants, stores, and the plaza Praça do Comércio. Before you arrival, look for email from the property NOT from the Expedia, it will contain the building access code. Without it, it may be hard to find a way in. After you get into the building, there is no front desk, instead you will need your booking confirmation number and passport to check-in and pay for the necessary city tax or fee. The final screen will provide building access code and room access code, take a photo. The apartment itself was super clean and modernized. We booked an studio since we stay for only one night, it has a small kitchenet, big closets, very comfy bed and a single sofa bed. When you checkout, just need to scan the QR code on the door, submit a simple form. Great service apartment overall, and will stay here again when we visit Lisbon.
