I was in Gulbenkian Park Residence for two weeks, and I was very good! The apartment is located very close to Museo Calouste Gulbenkian and to Metro Stasion Sao Sebastiano! Everything is very comfortable, and the Hosts are nice people and very kind. The only negative aspect is the absence of elevetor, and the apartment is on 4th floor, if you have a big luggage, it's hard!
