The apartment was exactly as described by Sandra. It is located in typical old building of this part of Lisbon, however it is very well maintained and contains all the possible services. The kitchen is small but well equiped. The bathroom is spacious. And, in general, the apartment is cozy and well located. You can reach by walk many interesting touristic points, restaurants, supermarkets and a couple of subway stations.
Sandra was very sincere, helpful and kind, and allowed us to leave the luggage in her house after the checkout.
In conclusion, totally recommended!
