Book it. This was one of the best stays we have had. Everything you could possibly need, comfortable bed, amazing bath tub, prime location, and the most hospitable crew. We loved our stay! They were going to let us leave our luggage with them since we got in in the morning, but we ended up even being able to check in early! The staff and Leven are good, hospitable people. We were even able to add a second day, and they arranged things so we could stay in our same room. Can't say enough good things about our stay! If you stay, grab a glass of wine from the bar in the lobby, and take it to your bath. Might have been the highlight of my stay. :)
One thing to note - if you are staying over the weekends, especially Saturday night, expect to hear some of partying from the street below. We did not mind at all - loved feeling apart of all the fun happening on Canal street. Our room over looked canal street which we enjoyed. But if you are looking for a super quiet stay, and wanting to stay over the weekend, you might want to ask staff about which room to book.
Do yourself a favor and stay at Leven!
