It’s a great location. Surroundings are therapeutic with plants and TREES. Please don’t remove the trees. Don’t use air conditioning ir heating. Don’t like being charged for other residents’ utilities. Expensive place to live for a senior cost of living.

The noise has gotten worse. The bldgs are between an alley way where delivery trucks arrive at 4 am, 5 am, to deliver. On the otherside we now have the Metro along with the rail train. The communication from the main office has gotten worse, I don't know if it is a change in staff or what. I call, leave messages, and I don't get a call back like I used to when Mickey handled it. Not sure if she is still there. Also I paid for my rental insurance thru AAA which you should have on file. Recently, I have started to get charged for insurance thru management. I am paying twice for rental insurance, which should not be allowed. I have asked numerous times to please correct the file and nothing has been done in about 3 months or so.

I have lived here for over 10yrs. Manager Micky Avila has served on the management team in one capacity or another this whole time and has always treated like family from the first day that I moved in. I hold both her and Assistant Manager Amaureen in the highest regards for their professionalism and concerns for this community and for all the tenants that live here. The improvements and activities that they have made here in the past couple of years has made it a great and comfortable place to live! Maintenance Supervisor Sergio is awesome, a one man team! Very knowledgeable, professional, and efficient. So far the best and hardest working maintenance man that has worked here in my 10 yrs of living here and would recommend it to anybody. Great job guys!
