Unfortunately we didn't get to meet the hostess who was very gracious in her messages . Her friend greeted us instead; she was in a bit of a hurry so we had to discover the apartment for ourselves. The space is airy and comfortable. The Wifi is good. There is a Nespresso coffee machine. The bathrooms are both on the main floor-- if you stay in the upstairs bedroom you have to negotiate a spiral staircase to get to the bathroom. A bit dicey in the middle of the night. We would have liked more blankets or duvets.
The apartment is indeed on the fourth floor with no elevator. But it's well located and very quiet. We would be pleased to stay again.
