Trine's apartment is cozy, as advertised. It is at a good location - on the junction of the 1st, 6th and 7th arrondissements - and a walking distance to the bus and metro stops. Nearest metro stops are Musee d'Orsay and Louvre Rivoli. One can easily walk to these two museums besides Place de la Concorde, Palais Royal, Jardin Tuileries, Eglise de la Magdalene, Notre Dame and other places.
The only inconvenience we faced was dust as repair works were going on in the stairwell and the lights were not functioning - though both were not a fault of Trine.
We enjoyed our stay
