My girlfriend and I loved this apartment - the view really is as breathtaking as the other reviews claim! Bruno was out of town when we visited Lisbon, but his friend Joana greeted us to hand over the keys and took the time to explain a few useful things about Lisbon, which we really appreciated.
The flat is, as you expect with such a view, right at the top of the city, but walking into the centre is not a problem, it doesn't take long and there are many interesting things to see along the way. Lisbon itself is great - when we were there, there was quite a lot of construction going on but this didn't spoil our enjoyment.
The apartment has everything you need and more - what an amazing place to wake up in! I can't recommend it highly enough.
