Everything is arranged to make your stay a good one. The hosts are paying a great attention to the guest's need. I loved the room where I stayed room 5. The aera is pleasant, very close to the Park of the Foundation Gulbekian, and to have a walk there is a must. The Museum is great.
As far as the Residence is concerned, as it is cleaned (every day) and tidy, the guests are keeping it so.
And I met nice people there. There's a Dishwasher, a Washing machine, and a large refregerator, nice dishes etc. etc...etc..
You'll have a nice time there !
