Both Silvia and Maël were great hosts! They were really helpful and guided us by giving us 2 maps and reccommendations about places to visit and eat in the neighborhood. As for the location it is the best you can get! Saint Germain is one of the best districts of Paris and the apartment was close not only to the metro but also within walking distance from Saint Michel and Notre Dame. You could also go on foot to the museums of Louvre and Orsay. There were other guests living in the house, but they were very dicreet and we didn't even notice them. The only downside was that we were 3 persons and as we were all girls we had trouble moving easily through our room with all our baggages and stuff. This room suits better for 2 persons, because it may be cute and a classical parisian room, but it can become really crowded with more than 2 persons, especially if there are only girls. Finally, the apartment is on the 4th floor and it comes without stairs. So, i would advise you not to carry heavy luggages, as i did. Hopefully, Silvia's mother was at the stairs the same time as me and Maël came and helped me lift them up.
