This place is also called "The Yellow House" in case there is some confusion.
I stayed here with 5 other friends and we had an amazing time. We reserved a 6 person cabin, which was awesome. Very clean, porches with beautiful views, and even our own hammock!
This guesthouse is a bit tucked away from the center of town, which we actually really liked because of the peace that it provided. It was an easy 5 minute walk down the driveway to get to town.
The highlight of the stay were the breakfasts each morning and the incredible service. The owners were so friendly and accommodating and we loved talking to them. Breakfast was delicious and served to us on our own private table on the porch. The views from the porch were awesome and we saw countless hummingbirds.
The Yellow House also has its own trails which we really enjoyed hiking and even saw a "Cock of the Rock!"
The only potential downside would have to be that there are 2 German Shepherd dogs owned by the hotel and they barked quite a bit overnight, whenever someone would arrive at the gate. It didn't bother me too much though.
Definitely stay here if you are planning a visit to Mindo! You will not regret it!
