The apartment is in an old building so it’s noisy. If you go during winter: it’s super cold as there is no heating in apartments in Portugal. Sonia provided 2 electric heaters but they could not be turned on at the same time due to risk of power outage.
If you are a family with children, know there is no lift and the stairs are quite steep and old. It was a hassle going up and down with a stroller as the apartment is located on the 2nd floor.
What bothered me the most was that all the area rugs (living room, bedrooms) were visible very dirty! Also the sofa pillows and throw.
Apart from that, the apartment is in a good location with many restaurant options nearby and easy connection to the rest of the city. It served us well (2 adults, 1 child). One of the bathrooms is really small but it’s ok.
