Had trouble with all the new technology. Had trouble entering the unit as it was the first time I had encountered those kinds of locks --- didn't realize you had to press some button first before entering the four digit code and then even after discovering this I had no idea that you had to press the check mark at the bottom too. Also, didn't know how to lock up. --- tried entering the code but this didn't work. Somebody had to tell me. Instructions on this would help. Secondly, I had no idea how to adjust the thermostat. There were no instructions --- fortunately the daytime setting was fine and to cool it off for sleeping, I was able to open all the windows. But at another time of year, this could have been a problem. Also, I never figured out how to get regular TV channels on the TV and which remote to use. Maybe it's just me...sorry. Anyhow, it was a beautifully clean property and the locations was superb! Enjoyed access to the pool/hot tub. Thanks for everything.
