Karls Apartment was very nice and very well located with grocery shops, cafes, restaurants and the 7 and 8 metro line all walking distance (within 5 minutes). You can walk to Sacre Coeur in 20 min. and to the Opera in 10 min. The apartment is perfect for 2 people. We enjoyed our stay i Paris very much and this apartment gave us the perfect starting out point to discover the city.
