Great stay in Lisbon! The apartment is cozy and very clean. It has air conditioning, the kitchen is well equipped, there's a closet to store your clothes, and communication went very well over WhatsApp. There's an elevator and checking in was easy and quick.
We've read some reviews about the street coming across as a bit 'dodgy'. I would describe it as a lively international neighborhood with a lot of small restaurants and stores. No one bothered us and we felt safe. The city center is just a 10-min walk away!
