The coquis are non-native invasive frogs and there are about a million of them in that neighborhood. If you shut all the windows (which was not fun, because it was about 85 degrees and 85% humidity, and no A/C), turn on the fan, use a white noise generator, and put in ear plugs, you CAN STILL HEAR THEM! They go from late afternoon to dawn and then the frogs go to bed and the neighborhood roosters start in. My wife and I are not from the area and did not know about them and were not forewarned. My wife could not sleep and was not happy. The "spa tub" probably fits someone about 5'4" or less, but I could not fit - and anyway, who would want to with all that heat and humidity and no way to cool down! I got heat rash as it was.
