Recounting my time down in Santa Teresa, it's hard to think that there might be a better place to rent than the Jungle House. As a group of 7, and for the price, I don't there is.
First off, the pictures do not do this place justice. Tons of space, hammocks everywhere, super chill upstairs with stereo/ping pong/bar/couches, full kitchen, pool, big charcoal grill... it's setup perfect for larger groups. We never felt like we were crowded, and everything was very comfortable. You instantly felt relaxed as soon as you stepped foot on the property.
Second, the location doesn't get much better than this. About 100m from the supermarket, 4 surf shops within 2min walk, surrounded by restaurants (honestly didn't have a single bad meal in 2 weeks), 5min walk to Playa Santa Teresa (which also has arguably the best and most consistent surf in the area), only 30min taxi to Montezuma, right across the street from a tourist info center where you can book all your adventures (Joe is also a great resource for this), about 30min walk to the bank and ATMs in Playa Carmen, and bike and ATV/motorcycle rentals are a couple minute walk. Plus the house is surrounded by jungle, with frequent visits from the howlers and iguanas. I'm not sure what else you would need.
Lastly, Joe was simply awesome. Very laid back and down to earth. He helped organize all sorts of things, from getting us fresh fish delivered right to the house (highly recommended), last minute taxi rides, where to go and eat and see, transport to and from the airport, and let us know of any special events that were happening in the area. He was always punctual in his email replies, and he was always just a phone call away. Chances are you'll see him around town or the beach, and anytime we saw him he would come check in and see how things were going.
For larger groups (families or friends) who plan on surfing or beaching it up everyday with the odd adventure here or there, this is THE place. You realize once you're here.
