A beautifully decorated flat though sadly situated so centrally that noise levels were a bit of an issue.
It is relatively newly renovated and well stocked with amenities (hair dryers, loo rolls, etc.) and very well connected to the surrounding Lisbon (though quite a bit of an uphill walk up from the nearest tube station). Significant positive - in bairro alto, there are a ton of small seafood restaurants around that are within 5 minutes walk away for some authentic Portuguese cuisine. Unfortunately, the noise levels were unbearable during both weekdays and weekends - thus leading to poor rest during our stay there.
