Though we never met Elsa she was very friendly, quick to respond and very sweet leaving us some wine and food. The apartment was well located, 5 minute walk from supermarkets and the underground. The bedroom was a great size and the electric fan was awesome in the summer heat!
The 5 story climb was a struggle after full days of walking around the city but what can you do. And the bathroom and kitchen were very small but we didn't stay long enough for it to become a nuisance. All in all the perfect little apartment for a weekend in Paris, would definitely recommend!
