We stayed at the Jb Relais Luxury, a couple with a baby for 5 nights during our vacation in Italy.
First, the room is very clean and spacious, even when there is a baby cot in it.
The room is well equipped with all the necessary amenities, including a comfortable bed, armchairs, wardrobe, mini fridge, safe, bathrobes, hairdryer, coffee maker, kettle, air conditioner, huge HD TV and more.
The hosts, Sebastien and Massimo were very nice, helpful and welcoming and even were available to our questions on the phone.
We received daily complimentary bottles of water, coffee capsules and fresh croissants.
As for the location - We found the place very central and within reasonable walking distance to all of Rome's main sights, Such as Piazza Navona, The Pantheon, Foro Romano etc. We liked it especially since the Trastevere area, which we loved very much, was right in front of us.
In addition, there is a supermarket right in front of the place, as well as dozens of bars and restaurants nearby.
In conclusion, we highly recommend the place, we had a great experience!
