I'm so glad I found this place by luck. Nueva Vida is completely different from the monotonous resort / day-club scene that prevails in Tulum. Frankly, the photos and listing here don't do it justice.
The grounds and garden setting are fantastic. Each bungalow or room is creative and different. If stairs don't bother you, Estrella del Amanecer (#18) was an excellent choice. The staff were helpful and friendly, sometimes going out of their way to help. Their English was excellent. When I asked how much (a common question in overpriced Tulum) for coconuts they opened for us, the staff member replied "free" when he could have charged.
Ricardo at the front desk was especially honest, genuine, and helpful.
The generous breakfast is held in a real restaurant -- better than the usual low-effort reception breakfast.
The WiFi was fast and reliable in our room.
Guests get a large jar of safe drinking water in their rooms refilled daily. Helpful for reducing plastic bottles, although not enough for two people for 24 hours. Daily housekeeping was superb. Shower was surprisingly hot. Mosquitoes are a nuisance after rains -- but that's the price for feeling like you're staying in a jungle!
Nueva Vida is -just- far enough from the thumping music that you can still hear it, but I didn't find it annoying. The beach area in front and little cabanas / mattresses were cozy and located away from the crowds.
I would 100 percent recommend this romantic place for a stay in Tulum!
