We absolutely loved this litte loft in Saint-Germain! It was everything we needed: right around the corner to the metro, walking distance from lovely cafes, markets and attractions and reasonably priced. Checking in was no hassle at all (we arrived early but were able to leave our bags while it was cleaned).
There was only a minor mishap with an electric outlet, I just needed to reset a breaker and the lovely concierge immediately assisted me. She doesn't speak much English but we communicated ok.
Ben and the concierge were great, answered questions almost immediately and really helped us have a great and peaceful stay.
Neighbors are ZERO noisy, no problems at all. The area seems very safe. ATM cash machine almost next door, there's also a Parisian cafe on the corner for a quick breakfast.
We were able to check out by noon on our last day. Definitely recommendable for folks that need a small place to stay in the heart of the old city.
