"Check in and check out was flawless. The kitchen was sufficient for making meals on vacation. The washing machine and dishwasher controls seemed a bit cryptic, an internet search cleared most of that up. I had brought a couple of microfiber cloths to aid in kitchen clean up, I am glad I did because I didn't find one on the kitchen. We also didn't find a washcloth in the bathroom, back to the I am glad I brought some cloths. The bathroom shelf lent it self nicely to all of our party to place their toiletries out. The bed that I slept in (we were a party of three) was very comfortable. The lounge are was very nice for well lounging. We did not eat breakfast there as we cooked in. The coffee shop on the ground floor was good and we stopped in several times. The unit that we were in was the larger 2 bedroom suite. "
