I highly recommend this place, it is clean, spacious, equipped with all the facilities you need and it is very close to all the major attractions.
Also, the owner Veronica and her husband Nuno are great people. They are very helpful by providing us a lot of information we need, very responsive and thoughtful.
My friend and I had a great experience there.
BTW, just small suggestions for Veronica. It will be nice if you can provide some mugs/cups for hot water; Chinese people love hot water. I was so scared to break the glasses if I pour into the hot water. Also, maybe you can also provide a cutting board and some kitchen knives (a big one).
