Read thoroughly Catarina' s and Alexandra' s first letter. They will send you a map where you can see everything you need. Also, give them heads up, what you wish to see on your trip, it will be a lot easier for the host(s) to make recommendations. And they make good recommendations.
What I loved about this place was that every possibility was in walking distance. One metro station is just 500m uphill and the other metro station is 800m downhill. It was the easiest to travel by metro. Also you had some bus stopes just in front of the house, but we used the metro mainly. And it took only about 25 minutes to reach the river - so excellent location.
