Steve was a wonderful host, available via cell for any questions leading up to and during our visit and offered some great suggestions. The house is very much as advertised located on top of the garage, attached to the main house. I'll break it down as follows:
1) Noise - The house is on the corner of Ruggles (a main street) and Carroll, which means you can hear traffic, fog horn or the garage. The hosts are really good about not opening the garage in the evening but the rest of course, can't be helped. It didn't bother us but for someone that's a light sleeper it may be of interest
2) Facilities/Cleanliness - The place is super clean and has a big room & bathroom with plenty of hot water (exactly what we needed). The kitchen is super small with a coffee maker (fabulous) and mini-fridge for some necessities. The hosts were great about keeping some stuff in the freezer (in the main house) for us. If you plan on really cooking, this may not be the best. The bed is soft and it creaks a bit so if one need a hard mattress, that will pose a problem. The wifi is intermittent, works best when in the living room. The TV is small and offers netflix via roku. We didn't need the latter much as we were out and about!
3) Location - It's nice living somewhere slightly more residential but still in the heart of it all. Ruggles leads directly to the Breakers (1/2 mile east) and to Ocean Avenue (1/2 south). We took advantage of the weather and walked as much as possible which was easy to do.

Enjoy.
