Really nice, spacious flat, very well located for visiting Lisbon’s old city, Graca, Alfama etc. We had several minor problems which were not fixed by the agency as they didn’t reply to our complaints. These included intermittent door alarm issue (which incurred the anger of the neighbour on first floor!), no toilet paper on arrival (basic!), blocked kitchen washbasin, TV not workin. We were eventually contacted on our last day by the agent who was very apologetic. She explained they had had a communications issue and offered us a later check out as a goodwill gesture.
We explained that although the appartment is great they need to create a guest information folder that explains how door alarm, TV, A/C etc work. They were receptive to our feedback.
The flat is very nice and we had a great stay. Given a 4/5 as those little issues were annoying.
