Great location minutes from metro and more room space than you're likely to get at the price range elsewhere (we were off season though, so rates may be different). Be aware that the free parking nearby was recently made green zone parking so rates can be as high as 8eu/day M-F to park. This is true of basically anywhere in Lisbon though. The space can run cool (which is great in summer!) and if you are there in winter she's made more than adequate space heating to keep things comfortable.
We were there for a month and felt very much at home.
