I stayed here for 4 nights in January 2012. The office I visited is in Ramat Gan; thus it was a convenient, walking-distance location. The hotel is adequate, with clean rooms, decent breakfast selection and a friendly staff.

You have to ask for none smoking treatment room because they do not have none smoking once or at least people don't follow the rules. If you ask when you reserve a room emphasize why it is important that you get none smoking or a treated room. Ask for the floor with high speed internet in advance. The service is great, the location is great, you can take a bus to Tel Aviv, Taxies are available 24 hours, and the breakfast is not so fancy but more than enough and well served. They also have a parking garage for free.

last Friday and saturday,25/26 nov 2011 my partner and I spent a very relaxing and quiet weekend at the optima rimonim hotel in ramat gan,simply not wanting to spend a fortune,and also not to be too close to the usual weekend crush on the seaside of tel aviv's hotels.
it was a spur of the moment booking,we didn't need the meals,so apart from breakfast on sunday morning before check-out.it was "enough"..not over board,nothing spectacular,but well presented and looked nice.way above the standard continental B/F.service unobtrusive
and pleasant.the room,(we received an up-grade without asking) was huge,the fixtures and fittings more than standard,just the bathroom very old and in need of good repairs.the vent in the bathroom was rather noisy.amenities provided were more than adequite.nice hotel without frills at a good price

Overall, I would not recommend this hotel.

I spent one unpleasant night at this hotel that was chosen for two reasons:
1. location - at the center of Ramat-Gan (please note that it's NOT located in Tel Aviv)
2. affordable price

I made a reservation directly through the Rimonim hotels website in advance and asked for a quiet non-smoking room.
The room allocated to me was on 14th floor facing a noisy street. I was very disappointed by a strong smell of cigarette smoke at the room. In addition, the walls between adjacent rooms are very thin, and I could hear all phone conversations that my neighbors had across the wall.
The room itself was of a standard size. The facilities included a small kitchenette equipped by a small refrigerator, microwave, a kettle, and a kitchen cabinet with a set of 2 plates and cups, as well as a very old TV. The cleanliness of the room, carpet (that was completely worn, with multiple stains), and the bed sheets was very poor. The mattress was not quite comfortable.
Hotel offers parking on the site at a discounted price (20 NIS for 24 hrs).
Pros:
- Wifi available at the room, without any extra charge
- Nice breakfast (dairy). Variety of cheeses, breads, croissants, pancakes, blintzes, cereal, Israeli salad, omelette, milk, orange/lemon juices (from a concentrate), coffee, tea

In sum, I would not use this place in the future.
