Can’t say enough good. From the moment we arrived till when we left the staff was great, the property immaculate, and couldn’t be in a better location. Great views, a lot of things were walkable and everything else was never more than a $10 uber ride away.

I will be back! I am hesitant to say how great this place was for fear of more people finding it and limiting my future stays. But I have to say this place was so chil and relaxing that everyone should stay here at least once if not more. I have recommended this place to several of my friends and you will too when you stay here. The bed was comfy, the breakfast was perfect before exploring and the staff was friendly and courteous. I am looking forward to our return trip, Enjoy!
