Hello all!
You talking about Kolomna hotel?There are several places to live there besides it.Radujnaya hotel is not far from DZ too and it is much better.I'm not sure about the price , but it something about 60 $ per room and four people can live there becouse it's 2-rooms.And it is yacht-club there, but it is much more expensive.And, of course, you can take the tent on DZ :)
