El Paraiso made our stay in Tulum easy, safe, and pleasant. They are a mature hotel and have systems in place for everything you'd need. The basics, such as drinking water, A/C, food, electricity, etc., made our stay comfortable. The parts we came for, like the beach, were as good as we expected. The special parts - such as our concierges, Abril and Cyntia - made it even more wonderful.
Tulum's hotel zone is built with no infrastructure. If you go to some other hotels, you might find that you get 1 bottle of water per day, that electricity goes out from 10pm-7am (the city shuts it off everywhere), or that you're exposed to the elements, or that there's loud music from the club next door at all hours of the night. El Paraiso has a big water refilling station, a generator so power is on 24/7, excellent hotel rooms with A/C, clean rooms with privacy, and is quiet.
The breakfast in the morning is really great. We were initially worried about the whole breakfast-at-your-hotel-room approach, since we don't really like room service in general, but this was not as it seems! El Paraiso's hotel rooms have these beautiful terraces with tables and chairs, and the breakfast is brought out there. All the breakfast food was wonderful and we ate as much as we wanted. We could walk over to the kitchen and ask for some granola, another cup of coffee, whatever - and they'd put it together with a big smile. They even made us sandwiches for lunch one day.
P.S., give Abril a raise!
