We stayed in Léon's loft apartment for 4 nights in November. Léon was a fantastic host, despite being on holiday himself at the time. He provided us with some great tips and recommendations for activities and restaurants. Léon was quick to respond to any of our questions, initially by email and then later through WhatsApp.
The location is absolutely the best part of the apartment. Quieter than the center City but within walking distance to basically everywhere. There are great bars, coffeeshops, a bakery, grocery etc all right in the same block as the apartment.
In terms of the apartment itself, it was exactly as described, clean, and had the basics for our stay.
No complaints all around!
