lisbon apartments

We have looked on lots of web sites for apartments in Lisbon. Has anyone rented from LisbonApartments.com? There are so many web sites out there it is driving us nuts finding one with king size beds, or at least two twin beds. Seems the only way to get an apartment with something other than a double bed is to get a three bedroom apartment. A queen size is acceptable but it seems to be double or nothing, no pun intended.
