Sub Hotel is located at 2 RER train station far from the city center, so it's not easy to say "I will have a walk here in the neighborhood" cause there's nothing around. Luckily, the train and bus stations are super close and it's easy to reach the city center!
Check-in and check-out were super and super fast, the staff is nice and they were ready to answer any questions!
The elevator is small, but big enough to carry a big luggage and 2 small girls like me and mum.
Breakfast was simple but had the essentials that could make it go through the day till dinner!
Talking about the room, we stayed on a Superior (room 38, at the end of the corridor) and it was big enough to fit 2 people, I can't imagine the Comfort rooms. The bathroom was nice, and renewed, missed only a couple of hangers for the towels to dry.
Bed was comfy enough, pillows a little bit less, but if you're really tired, it works!
Attention to the heater! You need to be able to use your phone in order to make it work.
