This place is more than a hotel room: It was indeed one bedroom apartment. I picked this place because I was travelling with two kids and needed extra bed, and we were coming in to Heathrow in the evening, and needed a quick place to stay before continuing on our trip next day. Having separate bedroom for kids was great. We also discovered that the kitchen had automated washer and driver, that we could do our laundry. It was fantastic, in the middle of a long trip.

This place would have ben even better if we are staying longer, and if I had my laptop to take advantage of internet service. Though close to the airport, the double pane windows shut the noise out and no problem with the noise.

Some problems: It appears to be OK to smoke in the hotel in UK still, and the living room where I slept smelled like cigarette, though it was not horrible. You may want to check the room before you accept it if you are sensitive. Also, no stores or restaurants on site. So get stuff before you go there.

Berkeley Apartments was dirty and a bit run-down. They are not accessible by the Hoppa. You can take the Hoppa to the Holiday Inn Ariel drop-off and then walk around the back of the hotel. The area seems a bit seedy and unsafe, especially with children. We booked the apartment, hoping to have a little more space for the children. There is not bar, restaurant, lobby, etc. There was a family downstairs cooking and setting off the fire alarms. The first room was overpowered by the smell of the BLACK MOLD, in the bathroom. The second room smelled of something else. The room was so gross, I would not allow my children to sit on the coach. We arrived back at the hotel late, and I was extremely concerned about saftey as we had to access the place by an darkenedWhen we re-entered the room, the windows needed to be shut because of the yelling down the alley. We would not stay again. Staff was very friendly and accomodating though.

Stayed one night.
All apartments are suites.
Check in was easy.
Its located behind holiday inn ariel, took the hoppa H6, but was told at check in that there is a free local bus service to the airport.
The hoppa doesn't start before 5am so had to take the local bus which run frequently.
Had a ground room suite which was big and clean, wooden floors.
The toilet/bathroom was very big.
There was a 30'' Flat screen TV with a DVD player.
The kitchen was adequately stocked(utensils etc)
There was a washing machine also.

Had problems connecting with the wifi internet access.

Lovely place to stay before my early morning flight.

Let's start with the good points. Clean, and excellent bed/bedding. But really it's just not comfortable enough. Very cold room on arrival and the under floor heating takes a long time to kick in. A wooden floor looks nice but I guess it’s the same in all rooms - I was woken early by someone clog-dancing above me. Getting back to sleep was impossible because the window blinds don’t keep out much light.
No shower, just a bath – not even a hand-held unit for rinsing hair. No hair dryer, no shelf for toiletries. Plus the hand-basin – surely the world's smallest - has no plug which isn’t great for wet shaving or the environment.
The kitchen was described as 'well equipped' so on the way down I grabbed a pizza for dinner and beans on toast for breakfast (yes, I know, I know). Sadly there was no oven for the pizza, only a microwave, and no can opener although there was a toaster. There was a hob – but no pans.
All in all, not enough to keep me away from hotels.
