The location is superb - nothing fancy - but it's within a short distance from all the touristic spots. If you are brave enough you can even walk to Belem from there. Groceries store is also close by, it's right in front of the metro station and there is a beautiful Oriental Market right at the bottom of the building. And the parking space is a huge bonus in Lisbon.
Communication was done through a third party - Lisbon Concierge - but was smooth and efficient all the way.
We were there with Izabella's parents and we stayed very comfortable.
The only one thing was the TV, the volume does not work and it's very low. But hey, one is on holiday, so that wasn't too bad.
Other than that, I'd surely recommend you to stay there.
