Maya Bell is as close as you get to the ruins in terms of accom. It's inside the national park and about a 20-30 minute walk up the road to the main entrance. The restaurant is really good. wi-fi has its problems, not very fast and has to be restarted on a regular basis - but at least you have internet there, none of the places in El Panchan do
Rooms are rustic and not entirely bug-proof (I had a room with a fan, not air-con) but when I was there (Nov) there didn't seem to be any mosquitos anyway, so not an issue. Shared bathrooms are a bit dirty. Being right in the jungle you get howler monkeys in the trees right above you. Amazing to be so close but this also means they may keep you awake at night or early mornings. Personally, I thought this was an incredible experience, but be warned they are LOUD! Being in the national park also means you have to take colectivos or taxis into town (and back). The walk to El Panchan take about 15-20 mins, I did it in the pitch dark along the road back and forth a few times without a problem

Maya Bell is rustic place with both cabanas and camping facilities. The restaurant was good, but the staff were not very friendly. Pool looked better at night than during the day. Cabanas near the pool are extremely noisy from pool guests due to the paper thin walls. The Cabanas were rustic nice nothing fancy. Maya Bell is very close to the ruins. It is easy and cheap to catch a collectivo to the ruins or into town.

We have stayed here a few times. Always consistent, secure, and comfortable. We always stay in the cabana rooms, but the campground looks great. Pool is huge, great food, music at night, and always an interesting crowd. We ran into 4 bicyclists riding through the Yucatan, Chiapas, then to Central America. We had just come from a month trip driving through Mexico, Belize Guatemala, and had the opportunity to share some info and tips with them. This is what traveling is all about, and the guests here are travelers. One time we have to stay in the tree house!

awful rooms, dirty, with cockroaches. the bathroom was almost destroyed, nothing was working properly. the pool was dirty and smelling although it was August and they were supposed to have it clean.
staff was rude, arrogant, unwilling to help or give information, even though they knew english they were pretending they didn't. the food was terrible and we had to wait more than half an hour for a beer to be served!!!
it is not the only hotel in the jungle, so they shouldn't promote in as something unique. as travellers we must not get so enthousiastic about a wooden house in the jungle! think twice before choosing it. People like them should not earn money as they do not deserve it!!!
