We had a great stay. The flat is on a small residential street, not far from cafes and shops. The rooms are quite small and don't all have windows but perfectly comfortable. The only problem was that it was very noisy at night (not partying - just animals and things), as we had to keep the windows open to stop from sweltering. This flat is a good base for exploring Lisbon, but quite small for 6 people, so maybe not if you're going to hang out there a lot.
