Great Value and Location

4.0 on September 04, 2015

This facility is essentially a Motel. It is very clean but nothing special. The Rate is very attractive, especially in the Walnut Creek Area. The downtown Walnut Creek Downtown Area is a short 10 minute walk and is very convenient. We only stayed overnight but it was a nice stay. The office lady was nice and the breakfast was a continental type w/ boiled eggs. A great value.

Decent overnight, simple

Simple rooms, nice that there was a fridge. Nice location to east bay sights. My only complaint would be the noise of the AC/fans. Even on low they were loud, and the freeway is close, so either with windows open or fan on it's a little noisy. All in all a good value for the east bay.

Very pleasant experience

This is a modest hotel that was very clean, comfortable, and conveniently located. Would stay there again. Staff was very polite and helpful and someone has a good sense of humor that is made evident in the signage. Live ivy decorating the overhang is a lovely plus.

Great little secret

In the expensive Walnut Creek area, this place is truely a great value. It is clean, staff is friendly. The interior is a little outdated with older wallpaper, but, but it's still cute. It backs up to the freeway, so there's a little noise but it actually works like "white noise" and we never have a problem sleeping here. We generally go out for breakfast, so I don't know how the food is, but we feel it's a great value and plan to stay here when we are visiting relatives.

Great location but could use some updating

Hotel is very well-located and free Internet is great. Room was very poorly lit. We had to move bedside lamp to the desk to have any lighting anywhere near the desk. Towels were hard to come by...needed to ask every day for two hand towels for two people. Innkeepers are well-intentioned but this place could use a bit of updating. Would gladly pay $10 more/night for these basic amenities.

A nice independent option

If you hate chains as my wife and I do, you'll find this is a nice independent option. A nicely updated motel near downtown, kept extremely clean by an obviously caring staff. We did not get to use the pool, alas, but that was a nice thing to find too.
