Diogo and Priscila's loft is a great place to stay at in Lisbon. It was very clean, modern, and is well maintained. The kitchen has all the basic needs to cook and eat comfortably, and the living area is also great for relaxing or working if needed. The building is conveniently located near a large metro station. It's a quick ride (or walking distance) to the touristy areas, but is located in a nice quiet neighborhood with a close supermarket, cafes and a large park. Also it was easy to communicate with Diogo and Priscila for any need.
This place is highly recommended for single or couples staying in Lisbon.
