Perfectly situated with short distances to "everything", we would surely recommend Albertos place. Clean and with good aircondition in all rooms - this was really appreciated!
We were 9 persons, which fitted fine in the four bedrooms. If you are MORE than 9, you have to start using the living room. Personally, I thing 14 is a stretch...
Also, you should be aware that the balconies and terrace mentioned are not really "outside" or open. Kitchen terrace was packed with washing machine and aircondition units and not possible to use. The other balconies are not really balconies, at least in the sense we expected. Apart from that - all good :-)
