This hotel was really easy to find (only literally about a three minute walk from the metro, Maubert Mutualite) and they have 24/7 access. They allowed us to leave our bags in the baggage room as we weren't able to check in until 3pm which was really helpful as we arrived very early on Eurostar. The girl on reception with the dark curly hair was absolutely lovely - she was there on our check in on Monday and when we left on Wednesday.
We did find the shower very slow to drain, however, and the hairdryer in the bathroom was AWFUL - it would literally have taken HOURS to dry my hair, so I had to ask on reception for a different hairdryer. They definitely need to ramp up the power for that! Also, the shower gel and shampoo were not refilled in the three days we stayed there and there was no conditioner which would have been helpful. They also didn't fill up the tea bags which also would have been nice. However, great location and small, but practical room.
