A lovely studio apartment. It rained in Lisbon when I was visiting and the studio remained nice, warm and cosy. The kitchen has also got a lot of bits and bobs to make cooking from home really easy.
Just a couple small things I'd say is that the hot water does run out quite quickly so if you're 2 people staying here, you might want to either have opposite shower schedules or have 2 minute showers (not the worst thing, its doable). The other small issue is that you can hear everything from outside (from walking and talking to cars etc) so if you're a light sleeper or find it frustrating being woken up a couple times, it might not be for you - it wasn't amazing but it wasn't a deal breaker for me.
