We (10) had an amazing weekend in Lisboa, and finding this cozy, bright, extremely central appartment certainly helped!
There really was enough room for all of us (even the two recently-finished-looking bathrooms were able to cope with ten people and all of their hairdryers every morning), the beds were comfortable (even the trundle beds had good mattresses).
Everything is really close by, and any form of transportation (tram 28!) is just minutes outside the doorstep.
Communications and check-in were also a breeze. We'd absolutely come back!
