We had a nice stay in the apartment which was very functional, cosy, and well-located. Helena provided us many useful information, maps and buses timelines at our arrival. There was also milk, tea, coffee and bread for breakfast. The only disadvantage was that the mattress in the bed was too soft, as well as the couch. Also, we didn't expect to hear so many planes arriving in Lisbon (it is probably the same problem in other apartments inside the center of Lisbon). Otherwise, everything went well.
