It is a cheap and basic alternative to a hostel. If you are not expecting anything fancy, you will be fine, especially in summer. Our main issue was a cold bathroom since it does not have a power socket to connect a heater (we were in Christmas time). The apartment has 2 small rooms and a kitchen with an electric plate and a microwave. A street is not fancy either, but it is very quiet and the area is safe. The nearest metro station is Avenida which is 5 minutes walking, Rossio is 15 minutes away. Supermarket is nearby. Antonio is very friendly and helpful. He was great about arranging an early check-in and a late check-out for us. Thank you, Antonio!
