We would definately recommend the Appartment for a four day stay! It is very well located in the middle of all the cool and nice places to visit, restaurants, next to the train station that leads you to Cascais. We had a very warm welcome with fruit etc. in the frigo, bread, tipps, flowers..we just felt like at home. Only minus: the appartment is on the top floor but not so bright. But as we were out all time it did not bother at all. Just perfect!
