Very confortable, very well situated. With more than all you can need to expend some days in Lisbon and perfect for a couple, little family or a group of 2 to 4 friends (we where 3). Clean al well decorated. The only limitation of this nice accommodation is the low ceiling, as said in the description. But it shouldn’t be a problem if you’re not bigger than 1’80m (6ft).
Next to Restaruadores and Rossio Metro stations, at less than 30’ walking from almost any attraction in Lisbon (unless Belem).
I would repeat my choice for this appartment without any doubt.
