Although we never got to meet Yael in person, she was able to provide exceptional service. There was 6 of us total and we fit perfectly - the space was so roomy we never felt cramped. The bathroom awesome and clean and there was plenty of hot water for a large group. The building has an elevator so we did not need to climb steps to the 4th floor. The is a prime location and in the heart of everything and also very close to the train station.
She was very responsive to our needs when we needed extra towels or anything else. We arrived in Paris a bit early and she was able to accommodate early check-in. She was also accommodating when we asked to hold our bags because we had a flight much later than the check out time. Overall, I would very much recommend this place!
