My friends and I had a wonderful time at Casa De Las Aguas - and would highly recommend it to others. The house/complex is amazing. It's almost a city block in size, combining multiple buildings, pools and terraces. Given the warm climate, everything is open to the outside, including the bedrooms and the bathrooms. (Insect repellant and earplugs for light sleepers are recommended.) The kitchen is well-stocked with everything you could possibly need for group dinners.
The location is also terrific. The house is located in the colonial neighborhood of Honda. If you forgot something or want to take a walk, the town is just outside your front door - but if you prefer, you can stay at home and feel totally secluded from the outside world. The drive was also quite easy - even with puente traffic, it only took about 3.5 hours from Bogota.
Finally, Luis, Hubey, Carlos (and the dogs) were a pleasure to deal with. Luis emailed me with all the details and phone numbers a week ahead of time (a first for me in Colombia!). The housekeepers, Hubey and Carlos, were incredibly welcoming and helpful.
All in all, a terrific weekend. I hope to visit again soon!
