We stayed here for one week in early October and the apartment is exactly as described/shown in the photos, with a lot of cooking utensils and also things like salt, oil, herbs and washing up liquid. This was one of the reasons I chose the apartment as we've found it annoying in the past having a kitchen without things like pots, plates and cutlery as then it's essentially useless! The apartment is also located around some really great restaurants so we went out for dinner some days too. It is also around 5 minutes walk from a good supermarket, which as other people have said is quite rare in Lisbon and also 5 minutes from Rossio station for the metro and train to Sintra. The wifi is excellent (better than we have at home) and we logged onto our Netflix account via the tv which was a great plus!
Juan was a great host and met us at the theatre on Rossio Square, which is a few minutes walk from the apartment. As many reviewers have said, it is up a very steep hill (which isn't paved too well) so we were glad that we had read these reviews and taken rucksacks rather than a suitcase. We are a couple in our late 20s/early 30s so are relatively fit, but we can see why the apartment may not be suitable for those who are less mobile as to reach the actual apartment you have to climb very narrow and steep stairs once inside the building. Anyone who is taller than around 5'8 has to duck! This is just representative of the age/style of the building/old Lisbon in general though. Juan then gave us a map of the city and drew on various places he recommended, which we found useful, including a fado place called Povo around 20 minutes walk away. This place supports young fado artists so is cheaper and "cooler" than a lot of the more touristy locations, and was really great. We did not contact him during our stay but he was more than happy for us to contact him (including to book restaurants, but we did this via TA) although we bumped into him when he was checking one of the other apartments in the block. He employs a cleaning lady who maintains very high standards in the property.
If you come into Lisbon on the metro then you'll already have a Viva card which is basically the Oyster card equivalent. This can be topped up at all metro/train stations if you click the "zapping" option. This can be used for all transit options (including elevators) in the Lisbon area (including Sintra, Cascasis and Belem) and dramatically cuts the cost. For example, an on board fare for the trams or funiculars are at least 2.85 whereas with the card it is 1.25. It also saves time queuing for what appeared to be a very long time to buy train tickets for Belem and Sintra, whereas we just turned up with minutes to spare, went through the barriers and got on the train as we would do in London. The viva card can also be used on the ferry for the Costa de Caprica but we had to pay cash for the bus from the ferry terminal, although they have plans to expand the Viva card network to cover this area in the next few months which would be more convenient for visitors.
