We stayed at the Dunn Inn for 2 nights - one at the beginning of our trip in CR & one at the end. The reception was friendly, but somewhat incompetent (ex: didn't realize he could contact Interbus when we asked him to look into options for getting to Monteverde).
The rooms are small, clean & simple. Beware that they can be very loud at night (there is a casino & restuarant with nightly live music across the street, which can be annoying - especially when you have to wake up extremely early the next morning to catch a flight.)

Don't expect the Ritz. Expect a simple clean room with TV, Mini Bar and very polite staff. No AC in our room but a nice ceiling fan. I'f your looking to save some money and feel safe and comfortable the Dunn Inn is the place to stay.

Easy to place to stay. The rooms are of good size, and able to provide quiet from the street. I have stayed twice at two different times and plan on going back. Plus the price is good compared to the other places to stay in the area.

My husband and I enjoyed the atmosphere at this hotel. A couple of annoyances keep me from rating it above average though.

First, we ate in the restaurant only once and found - count 'em - 3 hairs in three different dishes. That's why we only ate there once.

Also, there was a peculiarity about the showerhead in our bathroom. It wasn't adjustable, and the stream pointed so far back that you would bump into the shower curtain constantly. Combined with the fact that the curtain was just barely long enough made for a swampy post-shower experience.

Everything else was nice or at least OK.
