We stayed in this apartment on our two weeks summer holiday in Lisbon (a family of four). The apartment is exactly like in the pictures. Nice, clean and very newly renovated. The location is lovely if you are a tourist as you have tones of things to do in the Belém area even though you feel more relaxed and peaceful then in Chiado for example.
If you plan to stay for longer periods of time (and especially in the summer) it can be a little pricey though.
We had an issue with the air conditioning (witch was disturbing especially because it was really hot outside during our stay), but apart from that, everything was perfect and well functioning.
Hope you will enjoy it as much as we did!
