We stayed at the Riverside for three nights and had a true "Jekyll & Hyde" experience. There are two different parts to the hotel, the original "old" hotel and the newer hotel tower. Our first night was had a room in the old hotel and it was one of the worst rooms we have ever stayed in. The room was small, dank and had a musty smell. The furniture was old, drab and worn; ditto for the carpet and drapes. The bed linens and towels were very old and worn. The double beds were small twin-size beds barely big enough for two people. The bathroom had old, worn fixtures, with a broken toilet seat, and the lighting in the bathroom was so bad that when you pulled shut the shower curtain to take a shower, the shower area was completely dark. We couldn't get any Internet service in the room, and to top it all off the walls were so thin that we could hear our neighbors having an amourous time at 4 in the morning.
The next day we insisted that they move us to a room in the newer Tower, and they complied, and it was like a COMPLETELY different hotel. Our room was spacious, clean, bright and new, with a great view of the skyline and ocean. The bed linens and towels were nice and new. The Internet service worked great. The bathroom was spacious and nice. Everything was quiet, too. And the location is fantastic.
I don't know what's going on with this hotel, but whatever you do DO NOT stay in the older section of this hotel. Insist in getting a room in the newer tower. Otherwise, you will be very, very sorry. I'd give a rating for our first night in the older section a "1" and our rating for the last two nights in the newer section a 3.5 or 4.
