Hi everyone! 😊 Looking for your recommendations for a house cleaner. I am having someone come tomorrow from BoardWalk Cleaning, however, wanted to see if there is anyone that you use or prefer. Open to options and suggestions. Thank you in advance!

Also interested how much does she charge?

R
Resident

Hi neighbors, this is definitely kinda silly but I was hoping someone could recommend what my thermostat should be at and what mode to have it on now that we’re entering winter! I like my place to be warm and comfortable but not hot and hopefully keep my bill not too high! Thank you in advance.

L
Resident

Not silly! I was wondering the same thing.. please help jaja

H
Resident

I put mine on heat heat mode at 73 due to the “auto” function (in my apartment) does not seem to work. I do have a tendency to turn off my thermostat when I go to work and when I come back 9 hours later my apt is still warm. Hope this helps.
