Paulo is a friendly guy and accommodated or request for an early check in for a very reasonable charge. He also gave us good tips about the neighborhood (grocery stores, public transport etc).
The place is centrally located and it is easy to explore Lisbon from here! It is also close to bars and young life which is good but also leads to noise at night. So if noise at night is an issue for you, please keep this in mind.
With some improvements to the amenities, this place could be even better.
