Everything went extremely smoothly, Luis & team provided us with very clear & detailed instructions on everything. The place is very conveniently situated almost in front of a metro station, and is fairly central in Lisbon, making it easy to travel downtown or to Bairro Alto by foot. There is a supermarket & many other stores barely one minute away.
On the minus side, the neighbourhood can be fairly noisy at night, though I always use earplugs, so not too much trouble. It can get quite dark if the appartment as the "light" curtains are quite heavy, and opening them up makes the place very visible from the plaza, diminishing privacy.
On the whole I really recommend the place, incredibly convenient, and great if you need to "live" in Lisbon for a little bit (rather than "just" a place to sleep at night).
